Question

Addition of which molecules from options given below can help overcome competitive inhibition of enzyme succinate dehydrogenase?

• A. Malonate
• B. Oxaloacetate
• C. Succinate
• D. Malate

Answer 1

The correct option is A Malonate

Malonate is a competitive inhibitor of the enzyme succinate dehydrogenate. Malonate binds the active site of the enzyme without reacting and so competes with succinate, the usual substrate of the enzyme.

So, the correct option is 'Malonate'.
