B
Electron transport chain
C
Oxidative phosphorylation
D
Glycolysis
Verified step by step guidance1
Understand that fermentation is an anaerobic process, meaning it occurs without oxygen.
Recognize that during fermentation, cells need to produce ATP to meet their energy requirements.
Recall that glycolysis is the first step in both aerobic and anaerobic respiration, where glucose is broken down into pyruvate, producing a small amount of ATP.
Note that in the absence of oxygen, the electron transport chain and oxidative phosphorylation cannot occur, so ATP production is limited to glycolysis.
Conclude that the ATP produced during fermentation comes from glycolysis, as it is the only process that generates ATP in the absence of oxygen.
