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.
Anaerobic respiration is the process of producing cellular energy without oxygen. Anaerobic respiration is a relatively fast reaction and produces 2 ATP, which is far fewer than aerobic respiration. Anaerobic respiration happens in the cytoplasm where glycolysis releases energy from glucose and fermentation recycles NADH back to NAD+. The metabolic process of respiration which is the release of energy from food comes in 2 distinct flavors anaerobic respiration and aerobic respiration.
