38. A poison that prevents the transfer of electrons from the last iron-sulfur cluster of Complex I to coenzyme Q is added to a suspension of actively respiring mitochondria. Which statement best describes the cffect seen? (A) ATP production would be reduced as fewer protons would be pumped out of the mitochondrial matrix. (B) ATP production would be severely impaired as this would completely block electron transport through the electron transport chain. (C) ATP production would be impaired as this would uncouple oxidative phosphorylation from electron transport. (D) This compound would have little to no effect on ATP production. (E) None of above is correct.

39. Which of the following is an advantage of using multiple steps in electron transport? (A) By using several steps, the net △G is higher (more energy is released). (B) More heat can be generated by using small steps. (C) More energy can be captured to synthesize ATP by using small steps. (D) Small steps allow for both more heat generation and more ATP synthesis. (E) All of these statements are advantages of using multiple steps.
