natima [27]

Answer:

C. Succinate is the substrate, and fumarate is the product.

Explanation:

Succinate is the substrate of the enzyme Succinate dehydrogenase, and as a product is obtained fumarate.  In this scenario, malonic acid plays the role of a competitive inhibitor because its structure resembles the succinate's, so they compete for the active site of the enzyme.  So,  A option is wrong because fumarate is not the product. B option is wrong too because malonic acid is an inhibitor, not the substrate.  Also, D is incorrect because malonic acid is a COMPETITIVE inhibitor, not a noncompetitive one. Finally, E can´t be true because malonic acid is not product and fumarate is the product, not an inhibitor.
