Internal respiration is the transfer of gas between the blood and cells. External respiration also known as breathing refers to a process of inhaling oxygen from the air into the lungs and expelling carbon dioxide from the lungs to the air. Exchange of gases both in and out of the blood occurs simultaneously.
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.
