In cellular respiration, a series of molecules forming an electron transport chain alternately accepts and then donates electrons. What is the advantage of such an electron transport chain?

A. The advantage of an electron transport chain is the production of a large number of reduced, high-energy intermediates.
B. The advantage of the respiratory electron transport chain is that oxygen is the final electron acceptor.
C. The advantage of an electron transport chain is that a small amount of energy is released with the transfer of an electron between each pair of intermediates.

Answer:
C. The advantage of an electron transport chain is that a small amount of energy is released with the transfer of an electron between each pair of intermediates.

    Under anaerobic conditions (a lack of oxygen), the conversion of pyruvate to acetyl CoA stops.A. Oxygen is an input to acetyl CoA formation
    B. Oxygen is required to convert glucose to pyruvate in glycolysis. Without oxygen, no pyruvate can be made.
    C. ATP is needed to convert pyruvate to acetyl CoA. Without oxygen, no ATP can be made in oxidative phosphorylation.
    D. In the absence of oxygen, electron transport stops. NADH is no longer converted to NAD+, which is needed for the first three stages of cellular respiration.

    Which of these statements is the correct explanation for this observation?


    D. In the absence of oxygen, electron transport stops. NADH is no longer converted to NAD+, which is needed for the first three stages of cellular respiration.
