Consider the following: 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. Which of the following is correct?

• Succinate dehydrogenase is the enzyme, and fumarate is the substrate
• Succinate dehydrogenase is the enzyme, and malonic acid is the substrate.
• Succinate is the substrate, and fumarate is the product.
• Malonic acid is the product, and fumarate is a competitive inhibitor.
