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.

Oxidative phosphorylation (or OXPHOS in short) is the metabolic pathway in which the mitochondria in cells use their structure, enzymes, and energy released by the oxidation of nutrients to reform ATP.his store of energy is tapped by allowing protons to flow back across the membrane and down this gradient, through a large enzyme called ATP synthase; this process is known as chemiosmosis. This enzyme uses this energy to generate ATP from adenosine diphosphate (ADP), in a phosphorylation reaction.
