Succinate Dehydrogenase Catalyzes the Conversion of Succinate to Fumarate

question 73

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.
-Based on this information, which of the following is correct?

• A) Succinate dehydrogenase is the enzyme, and fumarate is the substrate.
• B) Succinate dehydrogenase is the enzyme, and malonic acid is the substrate.
• C) Succinate is the substrate, and fumarate is the product.
• D) Fumarate is the product, and malonic acid is a noncompetitive inhibitor.
• E) Malonic acid is the product, and fumarate is a competitive inhibitor.
