The answer is C. Organelles
the answer is the first one: by producing random changes in an organism's genetic code
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.
Basically it helps with reproduction in flowers by carrying a male gamete from one flower to another and then fertilizing in cross-pollination with the pistil of another flower.
hope this helps :)
