Vedclass · Answer

(D) The correct answer is $(d)$. Succinic dehydrogenase is an enzyme that catalyzes the oxidation of succinate to fumarate in the Krebs cycle. Competitive inhibitors are molecules that resemble the substrate in structure and compete with the substrate for the active site of the enzyme. Both malonate and oxaloacetate are structural analogs of succinate. Therefore, they bind to the active site of succinic dehydrogenase, preventing the binding of the actual substrate (succinate), and thus act as competitive inhibitors.
