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).
explain why cellular respiration produces so much more atp per mole of glucose than fermentation in terms of the total free energy changes involved the free energy drop from glucose to oxygen or another electron acceptor during cellular respiration is much greater that the free energy drop from glucose to pyruvate during fermentation thus there is more free energy available to use in synthesizing atp
