Aerobic respiration yields approximately 36 to 38 molecules of ATP per molecule of glucose, a yield vastly superior to anaerobic processes. The energy liberated during the movement of electrons down the transport chain is used to pump protons across the membrane.
Oxygen Accepting Electrons to Preserve Food and Prevent Spoilage
Oxygen has a strong tendency to attract electrons, positioning it high on the standard reduction potential table. These electrons carry a negative charge and energy derived from nutrient breakdown, and oxygen acts as the final destination, combining with protons (H⁺ ions) to form water.
This reaction effectively neutralizes the highly reactive electrons, preventing cellular damage while capturing their energy to produce ATP. The molecule’s ability to accept electrons cleanly—forming water as a byproduct—makes it an ideal terminal electron acceptor.

The resulting electrochemical gradient creates potential energy, which ATP synthase then harnesses to phosphorylate adenosine diphosphate (ADP) into ATP. The Mechanism of Electron Acceptance To understand why oxygen is such an effective electron acceptor, one must look to its molecular structure and redox potential.
