Which stage of cellular respiration requires oxygen that you breathe?

Question

Quizplus · Accepted Answer

The citric acid cycle and the electron transport chain both require oxygen. Oxygen acts as the final electron acceptor in the electron transport chain, which is essential for the production of ATP. Oxygen is not directly used in the citric acid cycle, but the cycle relies on products from the electron transport chain that requires oxygen, linking their oxygen dependencies.
