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 anaerobic respiration, which occurs during fermentation, less energy is extracted â only two ATP molecules per glucose molecule â because the products of the process, such as ethanol or lactic acid, contain more energy than does carbon dioxide, the product of aerobic respiration.n anaerobic respiration, which occurs during fermentation, less energy is extracted â only two ATP molecules per glucose molecule â because the products of the process, such as ethanol or lactic acid, contain more energy than does carbon dioxide, the product of aerobic respiration.
