The equation for respiration is C6H12O6 + 6O2 -> 6CO2 + 6 H2O + 36 or 38 ATP. This is known as aerobic respiration because it requires oxygen as a final acceptor of electrons.
Cellular respiration is the process by which cells use the energy that has been stored in glucose to synthesize adenosine triphosphate, or ATP). Glucose is broken down completely in aerobic respiration and is oxidized by the removal of electrons. approximately 3,000 kJ mol-1of energy is released during aerobic respiration.
Cellular respiration that does not require oxygen is called fermentation. In fermentation, glucose is partially broken down to create 2 ATP.
