Question 1

1.

Vmax is a characteristic of Rate of reaction vs. substrate concentrationg graphs. Draw a curve to show the typical rate of reaction as substration concentration increases, and label where Vmax would be.

Question 2

2.

In the previous question, you drew and labeled a graph showing Vmax. Please describe how the rate changed as substrate concentration increased, and WHY it changed in this manner.

Question 3

3.

Enzymes are known to be both specific and reusable. Explain these statements.

Question 4

4.

Vmax changes depending on if the enzyme is exposed to a) no inhibitors, b)competitive inhibitors, or c) allosteric inhibitors. On the graph provided, please draw a representative sample of curves for the same reaction, but influenced by a), b), and c). Be sure to label each curve as such. Then describe in the space provided WHY there is a difference in these curves.

Question 5

5.

Please explain what is happening to an enzyme-catalyzed reaction shown in the graph here, and WHY this is occuring.

Question 6

6.

This graph is showing a change in potential, or free energy, as the reaction proceeds over time.
a) what is the delta G?
b) is this reaction endergonic or exergonic?
c) what is the uncatalyzed activation energy required?
