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.
Aerobic respiration (with oxygen) can produce 36 to 38 ATP molecules from each glucose molecule. 1  Anaerobic respiration (without oxygen) only allows glycolysis to continue which produces 2 ATP molecules from each glucose molecule. 2  Therefore, aerobic respiration is some 19 times as efficient as anaerobic respiration.
