Quizplus · Accepted Answer

Fermentation is an anaerobic glucose-breakdown pathway that produces ATP without the use of an electron transfer chain. Glycolysis is the first step in both aerobic respiration and fermentation, but fermentation diverges from aerobic respiration by producing ATP through substrate-level phosphorylation instead of electron transport chain. Cellular respiration and aerobic respiration both utilize an electron transport chain. Anaerobic respiration typically also involves an electron transport chain, although it uses a different final electron acceptor than oxygen.
