The Krebs cycle requires oxygen, because...
without oxygen, NADH cannot be oxidized to continue receiving electrons as NAD+
without oxygen, coenzyme A is unable to be added to the pyruvate molecule to make acetyl CoA
without oxygen, ATP cannot be synthesized by substrate level phosphorylation
without oxygen, glycolysis cannot take place to provide the starting materials for the Krebs cycle
