D is correct answer as Endo means inside the host
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.
It might be carbon, I think this because of the pencil having graphite which is made of carbon.
If I remember correctly it should be 10%.
