Fermentation releases CO 2, but does not make any ATP â all ATP during anaerobic respiration is produced during glycolysis. Since glycolysis produces 2 ATP, anaerobic respiration yields 2 ATP for every molecule of glucose. Both glycolysis and fermentation take place within the cytosol/cytoplasm of a cell.
The product of this pathway is carbon dioxide and water and energy in the form of ATP. Most of the ATP produced by aerobic respiration is made by oxidative phosphorylation. Aerobic respiration takes place in three stages glycolysis, TCA cycle and electron transport chain. Glycolysis - In glycolysis molecules of glucose in the cytoplasm are broken into molecules of pyruvate. One glucose molecule yields two molecules of pyruvate.
