Regular cellular respiration is aerobic (requires oxygen), but some simple organisms can only do anaerobic cellular respiration for every sugar molecule broken down, but it isn't dependent on the oxygen supply. And it makes a waste product called lactic acid. Aerobic respiration Aerobic respiration requires oxygen. It happens in cells when glucose reacts with oxygen. Here are the word and symbol - higher only - equations: Glucose + oxygen ? carbon dioxide + water (+ energy) C6H12O6 + 6O2 ? 6CO2 + 6H2O (+ energy) Anaerobic respiration Anaerobic respiration does not need oxygen. It happens when there is not enough oxygen for aerobic respiration. ...read more.
