Aerobic respiration, a process that uses oxygen, and anaerobic respiration, a process that doesn't use oxygen, are two forms of cellular respiration.
Cellular respiration is a series of metabolic processes which all living cells use to produce energy in the form of ATP. In cellular respiration, the cell breaks down glucose to produce large amounts of energy in the form of ATP.Cellular respiration can take two paths: aerobic respiration or anaerobic respiration.Aerobic respiration occurs when oxygen is available, whereas anaerobic respiration occurs when oxygen is not available.The two paths of cellular respiration share the glycolysis step.ellular respiration can take two paths: aerobic respiration or anaerobic respiration.
