Answer and Explanation:
Cellular respiration is the process through which organic compounds are broken down enzymatically to release energy in the cell. Aerobic respiration takes place in cytoplasmic organelles called mitochondria. Glucose is completely broken down through oxidation to carbon dioxide and water with the release of a large amount of energy(38 ATPs). It takes place in presence of oxygen. anaerobic respiration is carried out by a number of microorganisms as well as muscle cells. Glucose is partially broken down in absence of oxygen into either lactic acid and energy(2 ATP) in animals or ethanol, carbon dioxide and energy( 2 ATP) in plants.
