Answers. Best Answer: That is precisely what it requires as also denoted by the word oxidative phosphorylation. It happens through the electron transport chain process and the proton gradient it creates. Substrate level phosphorylation does not require oxygen, it occurs during glycolysis and the Krebs cycle.Source(s): greendawn Â· 7 years ago.t happens through the electron transport chain process and the proton gradient it creates.

Aerobic respiration requires oxygen because oxygen is the final electron acceptor of the electron transport chain in the mitochondria. If there is no oxygen to accept electrons, then the electron transport chain stops working and the high energy molecules NADH+H and FADH2 cannot be converted back into NAD and FAD.
