The primary role of oxygen in cellular respiration is to:
| 1. | yield energy in the form of ATP as it is passed down the respiratory chain. |
| 2. | act as an acceptor for electrons and hydrogen, forming water |
| 3. | combine with carbon, forming CO2. |
| 4. | combine with lactate, forming pyruvate. |
