Malonate in citric acid cycle

WebMalonate is an inhibitor of the citric acid cycle. which of the steps (6,7 or 8) do you think inhibits?. explain your choice and describe the type of inhibition this molecule would cause and why you think it acts as an inhibitor. you need to explain your logic and your words.- WebC 98. In the citric acid cycle, succinate dehydrogenase catalyzes the conversion of succinateto fumarate. This reaction is inhibited by malonate, which resembles succinate but cannot be acted upon by succinate dehydrogenase. Increasing the ratio of succinate molecules to those of malonate in the reaction reduces the inhibitory effect of malonate.
