4) Describe how an enzyme works/ describe the lock and key theory.
5) The graph below shows how the rate of reaction of an enzyme changes with temperature.
a) Explain why the rate of reaction for the enzyme increases as the temperature increases from 10°C to 37°C.
b) Explain why the rate of reaction for the enzyme decreases as the temperature goes above 37°C.

6) The graph below shows how the rate of reaction of an enzyme changes with pH.
a) Why does the rate of reaction for the enzyme decrease when the pH decreases from 7?
b) Why does the rate of reaction for the enzyme decrease when the pH increases from 7?
7) The graph below shows how the pH affects the rate of reaction for 2 different enzymes; enzyme A and enzyme B.
b) Why does the rate of reaction for the enzyme decrease when the pH increases from 7?
7) The graph below shows how the pH affects the rate of reaction for 2 different enzymes; enzyme A and enzyme B.
One of these enzymes is found in the mouth, and the other is found in the stomach.
By looking at the above graph, which enzyme do you think is found in the stomach? Explain your answer.
