Definition and synonyms of key from the online English dictionary from Macmillan Publishers Limited.
Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.his potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group. Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
Through cellular respiration the cells harvest energy stored in food by a catabolic pathway for the production of adenosine triphosphate (ATP). ATP is a high energy molecule which is spent by working cells. Cellular respiration takes place both in eukaryotic and prokaryotic cells. Cellular respiration can be aerobic respiration in the presence of oxygen or anaerobic respiration in the absence of oxygen. There are two types of cellular respiration: Aerobic and Anaerobic respiration. Aerobic Respiration. Aerobic respiration takes place in the presence of oxygen, by which ATP is is produced by the cells by oxidation of organic compounds.
