Which process occurs when O₂ is unavailable to a cell?

Question

Quizplus · Accepted Answer

When O₂ is unavailable, the cell cannot perform oxidative phosphorylation, which ultimately leads to a lack of ATP production. In the absence of O₂, the cell can still carry out glycolysis, but without the availability of oxygen as the final electron acceptor, the electron transport chain cannot function properly. As a result, the cell may resort to fermentation to generate ATP through substrate-level phosphorylation.
