Electron transport chain:
A)involves transfer of O₂ to electrons in the substrate
B)results in a net consumption of ATP
C)can be thought of as electrons acting as fish increasing in energy as they jump up a waterfall
D)none of the above

Question

Quizplus · Accepted Answer

The electron transport chain involves the transfer of electrons through a series of complexes to ultimately reduce oxygen to water, not transfer oxygen to electrons. It results in the production of ATP, not consumption, and electrons lose energy as they move through the chain, similar to fish moving down a waterfall.
