Question 1

Repeat question 89, 90.

Answer 1

repeat

Question 2

know the structure of glycerol-3-phosphate?

Answer 2

What is it?

Question 3

A homodimer would show how many bands on a native and SDS-PAGE?

Answer 3

A homodimer would show only a single band, and that is because the subunits of the dimer are the same molecular weight.

Question 4

glycerol is most likely to use what type of bonds?

Answer 4

Hydrogen bonds.

Question 5

If both ATP and glycerol occupy the catalytic cleft and glycerol binds first, it means that?

Answer 5

That a ternary complex is formed, and since glycerol binds first it is an ordered mechanism instead of a random one.

Question 6

The presence of what amino acid indicates that the peptide could form a disulfide-linked dimer?

Answer 6

Cysteine (C)

Question 7

What is the most likely shape of the curve for the unfolding of proteins?

Answer 7

The unfolding of proteins is a cooperative process. And cooperative processes are marked by sigmoidal curves.

Question 8

How do you measure the catalytic efficiency of a enzyme and which relative values would produce the lowest catalytic efficiency.

Answer 8

Kcat/Km the lowest catalytic efficiency would be the result of a high Km and a low Kcat

Question 9

How is the coefficient of viscosity different in smaller in diameter blood vessels versus the larger ones?

Answer 9

There is a reduced viscosity force in smaller vessels and a larger viscosity force on vessels that have a larger diameter.
