Oxygen is the key for generating energy in cellular respiration.
Explanation:
The cellular respiration is a complex biological process that breaks down sugars, fat and proteins and transforms these materials into energy for the functioning of the organism. Oxygen is needed at the end of this process, when electrons liberated in the respiration are transported through the inner membranes of the cells, and the oxygen "attracts" these electrons and makes possible the production of great quantities of chemical energy in the said membranes.
