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.
Cellular respiration is a special process where cells produce energy in the form of ATP (adenosine triphosphate). There are two types of cellular respiration, namely aerobic and anaerobic, which the cells can use to produce energy, depending on the availability of oxygen. The literal meaning between aerobic and anaerobic lies in that the former process is carried out with oxygen while the latter without oxygen.
