Which of the following can greatly affect the speed of an enzymatic reaction?

I. pH
II. temperature
III. presence of inhibitors
  1. I only
  2. II only
  3. III only
  4. I and II only
  5. I, II, and III only
Explanation
Answer: E, I, II, and III only. All of these factors can affect the speed of an enzymatic reaction.

Key Takeaway: Depending on the factors involved, changes in any of the above factors can affect the speed of an enzymatic reaction. Enzymes typically work in narrow pH and temperature windows, so changes in either or both can greatly reduce the speed of the reaction. The presence of an inhibitor can also reduce the speed of the reaction.
