Distinguish between the following: (a) Aerobic respiration and Anaerobic respiration
Cellular respiration is process that involves breakdown of products that we eat to give us energy. It is a process in which products are oxidized to release energy. Respiration can be aerobic or anaerobic. Aerobic respiration results in complete oxidation of the respiratory substrate in presence of oxygen and thus more energy is released. Unlike aerobic respiration, partial oxidation of respiratory substrate takes place in absence of oxygen resulting in lesser release of energy during anaerobic respiration. Anaerobic respiration takes place in lower organisms and muscles of higher organisms whereas aerobic respiration takes place in mitochondria of higher organisms. Final answer The difference between aerobic and anaerobic respiration is as follows: Aerobic respiration involves the complete oxidation of respiratory substrate in presence of oxygen whereas anaerobic respiration involves partial oxidation of respiratory substrate in absence of oxygen. Aerobic respiration yields water, carbon dioxide and 32 molecules of ATP on complete breakdown of glucose molecule whereas anaerobic respiration will yield only two molecules of ATP along with carbon dioxide and ethanol.
