Just like in the lab experiment, adding iodine and Benedict's Reagent changed the color of the tested substances.
name: manuel s,period 1
it was the same except funner in real life
name: sergio .L
period : 1
if you change the ph3 ph5 ph7 ph9 ph11 to other maive your results go to other and no the same's
In carbohydrates the water turned a light blue and the glucose turned red. In everyday foods iodine turned dark brown.
Blog.1
The results of the both eperiments were the same. Everything came out the same the only difference was that we did one physically and the other on a computer.
Blog 1.The organic compound lab was very similar to what we did in class because we did the same exact test. only difference is how we are doing the testing, one was virtually and one was physically. The Glucose came out the same as it did in real testing.
In Carbohydrates, the water turned a light blue & the glucose turned red. In everyday foods, iodine turned dark brown.
in carbohydrates everything started out clear then when we added benedicts reagent colors started to appear.then when you added hot water bath the colors changed again in glucose, onion juice, and patato juice.
1. The organic compound lab was very similar to what we expirienced in the class room because we did the same exact tests only virtually and physically. In the virtual lab we found that the same things that we used in the physical expiriment were involoved in the second virtual expiriment. We expirienced similar results reaction wise for the two expirirments and we noticed that there might have been some different substances. All in all it seemed like the same expiriment twice.
Blog #1: Physical lab was harder than the computer lab.
Blog #2: (1)Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction. Is this a linear relationship? What happens to the initial reaction rate as substrate concentration increases?
- It's a slow process.
No.
It also increases
(2)What is the maximum initial reaction rate for this enzyme at pH 7?
- above 350
(3)Explain why the maximum initial reaction rate cannot be reached at low substrate concentrations.
- Becauase it is not mving fast enough to change itself.
(4)What does your data indicate about the optimum pH level for this enzyme-catalyzed reaction?
the lab we did in class is somewhat similar to the virtual lab. Both the 1st and 2nd virtual lab compare protiens and lipids and other substances in which some we did in class. when in the emperiment when added the benedicts the test substance turned a green/blue. The protein turned purple as perdicted. Both experiments are simalar in many ways.
the computer lab was way fast and it wasnt as fun. the other lab in class was alot funner(:.!!!!!!

They are alike because in class we tested for sugars. We used water as a control for all our experiments. They're different because we never tested for proteins. We tested fats with brown paper instead of Sudan III.
They were alike because most of them react. They are different because diet coke and water don't react.
They were alike because it was the same aspect of the experiment but they were different because the computer lab was more accurate
They were alike because they all had to be in hot water.
They were diffrent because they all had a diffent reaction.
the similarities between the two labs are that we were able to see the reactions and the difference was that for the lab in class we were visually able to see the changes.
Today's online lab and Friday+Monday's lab are similar by the way the reactions and changes in color occurred. These labs are different by the types of variables that we used during them and the lab from Friday and Monday is hands-on while the lab from today occurrs online.
The experiments were the same by us testing for the same things like proteins and lipids. The experiments were diffrent by the online experiment being shorter and more accurate versus in class where error could have occured.
the diffrences ,the real lab was more like didnt really switch colors except to blue and had less water. the virtual lab was more colorful had more colors changing , also had way more liquid in it. there the same by having like the same liquids to choose from.
The lab in class and the lab on the blog were the same because they used the same type of experiments. They are diffrent becuase the real lab didnt really have any major changes and in the lab on the blog ther were more things to expermient.
They were alike in the aspect of the the solutions,and the end results. They were diffrent in the things used to test.
comparisen:there the same because we did the same thing on the blog that we did in class.
contrast:there different because we did not get our hand's on the lab
In both labs we did the same type of experiments. except in the virtual lab it showed a different way for testing.
surgers and starches were the same and the protains and fats were different
they are similar because they both have to do with different chemicals, they all change colors, and they both use lipid. they are different because in the virtual one we did the protien test but in the reality one we didnt, this one is virtual,and the other one is real. :D
Compare :I thouhgt these labs were similar because we used the same solutions and testtubes , we also used the hot water bath ,and we watched the colors change.
Contrast: They are both different because in the real life one we didn't do the protein lab at all and in the lipid lab we used paperbag in real life than the test tube.
I thouhght this process way very useful and helpful for people who want to know whats really in their food. I will definitely try to remember this for future use.
The 2 labs were alike because we watched the colors of the subatance in the test tube change.we used iodine in both labs.the different was,we did a different test for lipids.we didnt do the proteins text as all.
The labs are alike because both showed reactions and we used iodin in both labs. but they also had diffences because we didnt do the protien tests at all and we did different equitment for lipids. we use brown paper for that.
the labs are alike because both showed diffrent reactions on each experiment ,and we used iodin in in both labs.There diffrent because we didnt do the protein test in class, also we did a diffrent test for lipids.
i think that the blog and the lab i did in class were similar because we watched colors change and the difference was that we didnt do the protien test at all and a total different one for lipds , we used brown paper to test instead of the tubes.
The labs were the same by, we were trying to figure out the same things. Also, the process was the same for the sugar and starch test. However, we didn't get to test the protein, and our process for lipids was different. Also, our numbers weren't exact like the vitural test.
The compare is sugar and starches are the same as the test we did as
Contrast is that we did not do protein
the labs are alike becuase it was the same procedure. they are different becuase some were unknown and were identified differently, also becuase we didnt do the protien test, and we used paper instead of sudain III from different experiment.
they are differnt because we didnt do the protain test. we used brown paper for the lipids test. for the same we watched the colors change. We added them to hot water.
The same was that the experiment was bascially the same. and the difference was that we didnt do protein in class.
The experiments were alike, because we did a few of the same tests, we followed the same procedures, and got the same results. Although they were alike in some areas, they were different in others because, we substituted the sudain III with paper and we didn't do some experiments at all.

the test were the same by the chenges the chemicals did.the comparison between the test are simular by the way we tested them.
They are the same because we used test tubes,the same solution. we also put them in hot water baths and watched them change colors.
they are different because in the real life test we didn't use the protein solution and we used paper bags instead of test tubes in the lipids experiment.
The labs were alike because we did Starch & Sugar tests.
The difference was that we tested Everyday foods like Apple Juice and Ritz Crackers.
This is boring.
The virtual lab was a lot less messy that's for sure. They're similar though because we used paper for the lipid lab.
both the virtual lab and the real lab used the same chemicals we did it exactly the same. we didn't do the protien lab. to test the lipids lab we used the paper and in the virtual lab we just needed to look at the orange circles.
Virtual lab and real lab are the same by seeing the suger, starch, and lipods in the items.Contrast is we did the experiment on paper and saw it with our own eyes, but virtual lab we did not comupter.

it was the same exact thing.
same types of material.
one we got paper to see if it was a oil or a fat.
In the virtual lab the colors were different then in the real lab, in this virtual lab we used the computer, we did the protein lab, on the lipids test in class we used paper to see if we could see through. In the real lab we actually used boiling hot water, in the virtual lab we used the "fake boiling water" on the web page.
The colors were the same in the experiment.
On the computer, we used protein. In the lab we didn't use protein.

what we did diffriently on the computer that we didnt do in class was the Lipids test. we used paper to test for light in class and SudanIII to test for color on the computer.
The virtual lab and the actual lab were different because we never tested the protein lab and also because when we tested the lipid lab we used paper towls to identify it instead of the sodium that turned orange. Every other test was similar to the actual lab done in class.
Virtual lab and real lab are the same by seeing the suger, starch, and lipods in the items.Contrast is we did the experiment on paper and saw it with our own eyes, but virtual lab we did not comupter.
In the lab the colors didn't come out to what the computer showed. In the lab my lipid didn't turn the color it was supposed to.
in both labs the colors change
They added different material on each tube. On class we used paper and online was virtual. They both are the same because they change colors....
because we test starch and suger.
This is boring
In the real lab,we didn't do the protein lab,but we did do the protein lab in the computer. We used glucose and iodine in the real lab and in the computer.
compare : they where both the same color we did the exact same experiment. contrast: we did it on the computer. we didnt use protein.
Lupita.Z, Dolores.C Jacob.F p6
The things that were the same in both labs were the change in color, the glucose, carbohydrate, and lipids test were the same. The contrast were that we didnt do the protein test and we used brown paper for the lipids test.
the things that were the same in both labs were the change in color.
We did glucose, carbohyrate, lipids, test in both labs. We didnt do the protein test. We used brown papper for the lipids test.
it was alike because the chemicals had turned alot of the liquids purple wich was positive, and it was contrast because not every test turned out positive.
The lab we did was different becuase we never tested protein. We also tested the lipid lab with paper towels to identify instead of sodium that turned orange. Some of the labs that we did were similar that we did inside of class in real life. It was more boring online then in the acual thing.
they were the same because the color changed in some of the expirements they way they were different because not all the things changed
they were the same because the color changed in some of the expirements they way they were different because not all the things changed
they were the same because the color changed in some of the expirements they way they were different because not all the things changed
they were alike because the chemicals had turned alot of liquids purle which made them positive
2. the activity of enzymes is strongly affected by changes in pH.
3. as the concentratraion of substrate increases, the rate of reacioin also increases until the point saturation occurs.
2. the activity of enzymes is strongly affeterd by changes in pH.
3. as the concentration of substract increase the rate of reacion also increase until the point saturation occurs.
2. The effect of pH on the initial rate of enzyme catalyzed reaction is that the pH changes the how the substances react becuase the pH is stronger and weaker.
3. The affect of substrate concentration on initial rate of enzyme catalyzed reaction is that the different substrate amounts change the reaction because smaller amounts are not as powerful.
it was similar to what we did in class.
the chemicals react differently with the plain substances.
Alot of the time with the pH3 pH5 and pH7, it usually blue. most of the pH3 and pH11, it is usually light blue.
Amber Palmer 2nd hour says that they were alike because they were all postive and when it turned purple they were all postive.
When I did the test in class, we had to wait for a reaction, but online, we didn't. Also, we did the protien lab online, but not in class. One other difference was that we used brown paper for the lipids test.
in the lab the only one we didn't do was the protein experiment... the test for sugar and starches are the same. test for proteins ,, lipid test was on brown paper to see light, virtual, sudan tn, . turned orange...
they where alike cause they all had to be in hot water
They are both the same because you get the same results. The only thing that is different is that it is more consistant and its on a coputer.
you had to add things to the test tubs an see what changes them and some of them didnt change
the comparising of the experiment and the experiment from the one in class is that they changed color while heated up. the difference is that we got to do the protien test on the computer. :)
Doing this testing online seemed to be much more efficient and a lot easier than the in class lab. It was more understandable than doing a hands on experiment.
Doing this experiment on the computer is a quicker way to finish it and it is was a lot easier and less dangerous to complete.
The lab on the computer is easier than the real lab because it's efficent and less dangerous
Just like in the lab experiment, adding iodine and Benedict's Reagent changed the color of the tested substances
surgar and starch test were exactly the same. we didn't do the proten test in the real lab. and we used paper bag to test for lipids in the real lab.
The virtual and real-life experiments were very similar and had almost the same resuslts. To do the experiment hands-on was a lot more interesting, though.
The labs are alike because they both used qualitative data. They are different because each macromolecule reacts to a different indicator.
the liqiud turn into a positive withch was purple
This was practically the same expirement only one was in real life and the other was a simulation on the computer. The organic compound lab was very similar to what we expirienced in the class room because we did the same exact tests. Only one was in real life and the other was virtually. In the virtual lab we found that the same things that we used in the real life expirement were involoved in the second virtual expiriment. We expirienced similar results reacting for the two expirirments and we noticed that there might have been some different substances in the virtual expiriment. :3
The virtual experiment and the real life experiment were very similar and had practically the same results. Performing the experiment hands-on was a lot more interesting, by far.
this was boring but kinda fun
\
We used brown papper on the lipids tast and did not use that on this one.
They were similar because of the liquids changing color.
The starches and sugars were exactly the same as the labe we did. We did the lipids, glucose,and carbohydrates test in both labs. we didn't do the protein test and we used brown paper for the lipids test.
They were alike because they both of them were postive and that they were same color and the same color had to be postive.
madisen brown 2 hour;
the effect of the substrate concentration on initial rate of enzyme catalyzed vacation is that hey stick together creating a lock and key kind of thin and the other question is that they change shape
If you change the amount of PH you use, than the amount of enzyme-controlled reactions also rise.
As the concentration of substrate increases, the rate of reaction also increases until the point saturation occurs.
The lab we did in class we had tested to see if it was a starch lipid, or sugar. In the virtual lad we did the same thing and we also used different substances. Also we tested to see if it was a protein, something we didn't do in the lab in class.
2. The pH increases the amount of molecules and it varies depending upon on how high or low the pH level is.
3.The substrate effected it because depending upon the amount of substrate the color changed.
The effect pH has on the rate of an enzymes catalyzed reaction is based the initial value of the pH
The more of a substance can effect the rate of a enzyme catalyzed reaction by causing it to react faster with more added
Virtual lab and real lab are the same by seeing the suger, starch, and lipods in the items.Contrast is we did the experiment on paper and saw it with our own eyes, but virtual lab we did not comupter. in this lab, you could see as you added different amounts of the substance to the test tubes, they would chamge color.
hector pd:1 I like the computer lab then the one in class cause it was easier
Enzyme-Controlled Reactions
Based on the data the more neutral the substances pH, the more it catalyzes the enzymes.
Based on the data the more concentrated substrate added, the more the enzyme reaction was catalyzed.
The pH starts off low then increases.
The amount of substrate increases the pH then decreases it.
Period 2.
In carbohydrates the water turned a light blue and the glucose turned red. In everyday foods iodine turned dark brown.
Period 2.
The ammount of substance can effect the rate of an enzyme catalyzed reaction by causing it to react faster with more added.
I liked the hands on experience better because I learn better that way
The virtual lab was a little similar to the one we did in class because we did use some of the materials and did do some procedures the same but they were different because we did not test the lipids the same we used paper bags instead of test tubes. it was also the same because we did test the other materials
The amount of a substance can speed up or slow down the rate of an enzynme catalyzed reaction.
2. Amount of molecules increase depending on the high or low pH levels of the substance
3. The color changes depending on the amount of substrate.
The effect of pH on the initial rate of enzyme catalyzed reaction was that the reaction rate also increased. The effect of substrate concentration on initial rate of enzyme catalyzed reaction was there wasn't enough substrate to react at its maximum potential.
2. The effect of pH on the initial rate of enzyme catalyzed reaction is that the lower the pH and the darker it is the slower the rate. The higher the pH and the darker it is the faster the rate. the lower pH the lighter it is the faster the rate. The higher the pH and the lighter it is the slower the rate is.
3. The effect of substrate concentration on the initial rate of an enzyme catalyzed reaction is that the less the substrate means a slower rate on a lower pH. The higher the substrate and the lower the pH gives it a faster rate.

The higher the pH and the darker it is the faster the rate. the lower pH the lighter it is the faster the rate. The higher the pH and the lighter it is the slower the rate is.
3. The effect of substrate concentration on the initial rate of an enzyme catalyzed reaction is that the less the substrate means a slower rate on a lower pH. The higher the substrate and the lower the pH gives it a faster rate.
2. the rate of an enzyme catalyzed reaction will increase molecules, depending on how high or low the pH levels of the substance.
3. The effect of substrate concentration on the initial rate is the temperature of the substance and the color of the substance.
2. the more basic the ph level is, the less molecule will be formed. and the more acidic the ph level is, the less molecules will form. so because 7 is neutral on the ph scale, that is why that is where the most molecules form.
3.obviously the more substrate there is added, the more molecules will form
2)The molecules can increase or decrease , it varies on what the ph level is.
3)Its speed and color increased the more you added.
mireya villela period. 3
This lab and the other labs are similar by the way the reactions and the color changes in the lab. These labs are also different by the types of variables that we use during the lab the lab on friday was hands on and we might have not gotten the right amount of iodine or the blue liquid. Then on the other hand on the computer they put the exact amount that they need to get.

period 2
liked the lab experiment, adding iodine and Benedict's Reagent changed the color of the tested substances, i leard alot and it was intersting

I had fun in this lab it was very cool with what we did
