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.
During aerobic respiration, oxygen is present, and helps the process to crank out energy very efficiently. Some organisms can also undergo anaerobic respiration, in which oxygen is absent and a somewhat less efficient method of metabolism takes place.ummary. What was built by photosynthesis, glucose, is broken down during aerobic respiration, releasing electrons in the process, which are crucial 'workers' in the manufacturing of ATP. During photosynthesis, the products of aerobic respiration are then taken in as reactants in building more glucose.
