Which process is most directly prevented in the absence of adequate oxygen?

Question

Quizplus · Accepted Answer

The electron transport chain requires oxygen as the final electron acceptor to produce ATP. In the absence of adequate oxygen, this process cannot occur. Glycolysis and the citric acid cycle can still occur in the absence of oxygen, but they will only produce a small amount of ATP through substrate-level phosphorylation. However, without the electron transport chain, the ATP yield will be very low. Therefore, option D is incorrect. Option E is also incorrect because glycolysis can still occur in the absence of oxygen.
