What is the role of oxygen in the electron transport chain?

Oxygen acts as the final electron acceptor in the electron transport chain. After electrons have been passed through the protein complexes, they are transferred to oxygen, which reacts with free protons to form water. This step is crucial because it ensures the continuation of electron flow through the chain, preventing a bottleneck that would halt ATP production and cellular respiration.
