What is the role of the oxygen molecules required for aerobic respiration?

A) To form ATP
B) To produce CO₂
C) To accept electrons directly from either NADH or FADH₂
D) To accept the low energy electrons at the end of the electron transport chain
E) To store high energy electrons that are passed to complex I of the electron transport chain

Aerobic Respiration

The metabolic process in which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Oxygen Molecules

Diatomic molecules consisting of two oxygen atoms bonded together, essential for the process of cellular respiration.

Electron Transport Chain

A series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.
