Cell Test

Question:
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.
