A competitive inhibitor of succinic dehydrogenase is:

A $Malate$
B $Malonate$
C $Oxaloacetate$
D $α -ketoglutarate$

Solution & Step-by-step Explanation

Competitive Inhibition:Succinic dehydrogenase is an enzyme of the Krebs cycle that converts succinate to fumarate. Malonate is a classic example of a competitive inhibitor because its chemical structure is very similar to the substrate, succinate. It competes for the active site of the enzyme, thereby reducing the rate of reaction.
