Question 2 which of the following accurately describe any difference(s) between oxidative phosphorylation and substrate-level phosphorylation during fermentation in eukaryotes? a. oxidative phosphorylation relies on energy initially derived from redox reactions to power atp synthase, and substrate-level phosphorylation relies on enzymatic reactions to phosphorylate adp. b. oxidative phosphorylation takes place in the inner mitochondrial membrane and substrate-level phosphorylation only occurs in the cytosol. c. oxidative phosphorylation uses oxygen as a substrate and substrate-level phosphorylation uses phosphate. d. oxidative phosphorylation takes place during glycolysis and the electron transport chain and substrate-level phosphorylation occurs during the citric acid cycle and chemiosmosis. e. oxidative phosphorylation does not take place during fermentation, but substrate-level phosphorylation does.
