Multiple Choice
Succinate dehydrogenase catalyzes the conversion of succinate to fumarate.The reaction is inhibited by malonic acid,which resembles succinate but cannot be acted upon by succinate dehydrogenase.Increasing the ratio of succinate to malonic acid reduces the inhibitory effect of malonic acid.The effect of malonic acid on the activity of succinate dehydrogenase suggests which of the following?
A) Malonic acid is a noncompetitive inhibitor.
B) Malonic acid is a competitive inhibitor.
C) Malonic acid blocks the binding of fumarate.
D) Malonic acid is an allosteric regulator.
