Verified step by step guidance

Understand the concept of aerobic respiration: Aerobic respiration is a process in which cells convert glucose and oxygen into energy, carbon dioxide, and water. It requires oxygen as the final electron acceptor.

Identify the role of the electron transport chain: In aerobic respiration, the electron transport chain is a series of protein complexes located in the inner mitochondrial membrane. Electrons are transferred through these complexes, releasing energy used to pump protons across the membrane.

Recognize the importance of the final electron acceptor: The final electron acceptor is crucial because it allows the electron transport chain to continue functioning. Without it, the chain would halt, and ATP production would cease.

Evaluate the options given: Sulfate, nitrate, and carbon dioxide are not suitable final electron acceptors for aerobic respiration. These are typically used in anaerobic respiration processes.

Conclude with the correct answer: Oxygen is the final electron acceptor in aerobic respiration. It combines with electrons and protons to form water, completing the electron transport chain and allowing ATP synthesis to occur.
