cellular respiration definition The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions (see metabolism) of an organism run. Note: The main carrier of energy in metabolism is the molecule ATP.
One way to view cellular respiration is to relate it to breathing. Both breathing and cellular respiration take in oxygen and release carbon dioxide. As you will see in this chapter, the oxygen made available to the cells of the body via breathing makes the aerobic portion of cellular respiration possible.
