Second Unit 3 SAC?

is the grounded liver and the liver cube representing SA:V?

Probably that the testtube with grounded liver would have a greater rate of  enzyme activity than the cubed liver because the SA:V ratio of grounded liver > SA:V ratio of cubed liver.

when the liver is grounded, wouldnt the bonds in the enzymes/proteins be broken, and so denture?  or is the grounded liver just to see if SA:V affects the reaction?

No, grinding the liver won't do anything to the proteins in the same way that cutting a piece of paper doesn't cause nuclear fission.

I think its only to investigate SA:V ratio

[Snorlax]

When high temperates denature enzymes, which bonds that determine the 3-D shape of proteins break? The hydrogen bonds, ionic bonds or the disulfide bridges? Or all 3?

[Daenerys Targaryen]

Usually hydrogen bonds ( ithink) because they are the weakest. So they generally break first

Disulfide bridges + ionic bonds are relatively strong, but denaturation would definitely disrupt the hydrogen bonds between hudrophobic and hydrophilic R-variable groups when investigating the tertiary structure of the enzyme  

[Bad Student]

As the temperature increases, the bonds would break in order from weakest to strongest.

(1) Hydrogen Bonds
(2) Ionic Bonds
(3) Disulfide Bridges

I had 4 kinds of liver, control, grounded, diced, and boiled.

and tested which was most effective.

covers surface area to volume ratios
denaturing of enzymes

Ended up doing the same prac. Unfortunately, there were a lot of experimental design questions, which are not my forte... I think I still I did alright, however.

good luck.
what do you meN experimental design questions?

[psyxwar]

good luck.
what do you meN experimental design questions?

Questions on hypotheses, controls, variables, potential errors in the experiment, etc.

[Yacoubb]

If you were asked to design an experiment in the exam, you'd have to include three main areas that encapsulate all of what psyxwr has mentioned, into these three headings:
(a) Hypothesis
(b) Method - includes control of variables, introducing materials/organisms.
(c) Findings that support/negate your proposed hypothesis.

Ahh got it.
Our 2nd SAC now only consists of Results (10marks) and Application Questions (40marks).
Damn happy that i don't need to focus on the experimental design like my last SAC...

[Snorlax]

I'v got a few question:
How is the active site of an enzyme formed?
Also, a cofacotor is a coenzyme, right?
could someone sum up the main points of the two?
thanks.
