The inhibitor X prevents coenzyme Q (Q) from participating in electron transfer in the electron transport chain. (a) Will the presence of X prevent electrons from N ADH from passing through the electron trans- port chain? Explain why or why not. (b) Compound Y is a non-physiological reducing agent capable of directly reducing cytochrome c1 in Complex III. Would oxygen consumption resume upon the addition of compound Y to mitochondria inhibited by inhibitor X? Be sure to explain your answer.
