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.

Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of cellular respiration. Without oxygen, glycolysis allows cells to make small amounts of ATP.This process is called fermentation.hese reduced forms carry the high energy electrons to the next stage. The citric acid cycle occurs only when oxygen is present but it doesn't use oxygen directly. This cycle takes place in the matrix of cell mitochondria.
