Verified step by step guidance

Understand the role of oxygen in biochemical processes: Oxygen is a key molecule in aerobic cellular respiration, where it acts as the final electron acceptor in the electron transport chain, enabling the production of ATP.

Review the process of fermentation: Fermentation occurs in the absence of oxygen and is an anaerobic process. It does not involve oxygen, so it is not relevant to this question.

Examine glycolysis: Glycolysis is the first step in glucose metabolism and occurs in both aerobic and anaerobic conditions. Oxygen is not directly involved in glycolysis, so it is not the correct answer.

Analyze Photosystem II of photosynthesis: Photosystem II is part of the light-dependent reactions in photosynthesis, where water is split to release oxygen. However, oxygen is a product, not a participant in this process.

Conclude with aerobic cellular respiration: Oxygen is essential in aerobic cellular respiration, specifically in the electron transport chain, where it facilitates the generation of ATP by accepting electrons and forming water. This makes aerobic cellular respiration the correct answer.
