The energy required to drive the synthesis of the majority of the ATP generated during aerobic respiration comes most directly from:
A)the movement of electrons through an electron transport chain.
B)removal of a phosphate group from another molecule.
C)the flow of protons through an ATP synthase complex.
D)sunlight.
E)the conversion of glucose into two molecules of pyruvate.

Question

Quizplus · Accepted Answer

The majority of ATP generated during aerobic respiration comes from the flow of protons through an ATP synthase complex. This process is known as oxidative phosphorylation and occurs during the electron transport chain. The movement of electrons through the chain creates a proton gradient, and the flow of protons through ATP synthase generates ATP.
