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.
In aerobic respiration in the mitochondria, there are 2 moles of ATP produced in the citric acid cycle (Krebs cycle) by substrate-level phosphorylation, and between 32 and 34 moles of ATP produced by oxidative phosphorylation through the electron transport chain and chemiosmosis.
