Addition of lot of succinate does not reverse the inhibition of succinic dehydrogenase by malonate.

Vedclass · Answer

(B) The correct answer is $B$. The inhibition of succinate dehydrogenase by malonate is a classic example of competitive inhibition.Competitive inhibition is a reversible process where the inhibitor competes with the substrate for the active site of the enzyme.Because the inhibitor is structurally similar to the substrate,it occupies the active site,preventing the substrate from binding.Since this binding is temporary and reversible,increasing the concentration of the substrate (succinate) allows it to outcompete the inhibitor (malonate) for the active site,thereby reversing the inhibition.Therefore,the statement that adding a lot of succinate does not reverse the inhibition is incorrect.
