During aerobic cellular respiration, molecular oxygen (O2) is used for which of the following purposes? It is incorporated into intermediate molecules in the citric acid cycle. It is utilized as a substrate to accept electrons during oxidation of pyruvate. It accepts electrons from Complex IV of the electron transport chain. It is utilized during fermentation to regenerate NAD+. It is the source of oxygen utilized to produce carbon dioxide.
