The role of oxygen in cellular respiration is to (d) act as the final electron acceptor. Oxygen is used in all main steps of the cellular respiration; in glycolysis, citric acid cycle, and oxidative phosphorylation. It attracts so much electrons more than any other proteins.
c. allow glycolysis to continue.

The reactions that are catalysed by enzymes actually helps the organism to grow, respond to various changes in the environment, reproduce and continue maintaining their own structures. Cellular respiration is also considered a part of the metabolism process. This process actually helps in carrying the oxygen through the blood.
