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.

Although glycolysis requires two ATPs, the reactions produce four ATP, two NADH, molecules that are used to drive ATP synthesis in the mitochondria and two pyruvate molecules. Although glycolysis doesnât require oxygen, the fate of the pyruvate molecules depends on whether oxygen is present. If oxygen isnât available, the pyruvate is converted to lactate, and no additional ATP is produced from this conversion. If oxygen is present, the pyruvates are transported into the mitochondrial matrix.
