33) Succinate dehydrogenase catalyzes the conversion of succinate to fumarate.

33) 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) fumarate is the substrate, and succinate is the product D) fumarate is the product, and succinate is a noncompetitive inhibitor E) fumarate is the product, and malonic acid is a competitive inhibitor 34) Which of the following options would increase the rate of an enzyme catalyzed chemical reaction that presently -3 -9 contains 10 M substrate and 10 M enzyme? 35) For living organisms, which of the following is an important consequence of the first law of thermodynamics? A) the e
