Malonic acid is an example of____________?
Correct answer: C. Competitive inhibitor
- A. Irreversible inhibitor
- B. Reversible inhibitor
- C. Competitive inhibitor
- D. Non-competitive inhibitor
Explanation
Malonic acid resembles succinic acid and competes with it for the active site of succinate dehydrogenase, so it is a competitive inhibitor. Students often choose reversible inhibitor because malonic acid binds reversibly, but competitive inhibition gives the more specific classification.
