Aerobic and Anaerobic Respiration

Aerobic

C6H12O6 + O2   → 6CO2 + 6H2O + 36ATP(energy)

Anaerobic - often called fermentation. This process represents the fermentation process eg yeast fermentation.

C6H12O6 →   2C2H5OH + 2CO2 +2ATP(energy)

Glucose             ethanol  + carbon dioxide

Aerobic respiration also occurs in muscle cells when there is a shortage of oxygen. This results in the formation of lactic acid. A build up of lactic acid causes the burning sensation we feel when we are exercising.

C6H12O6 →  2C3H6O3 + 2ATP

Glucose            Lactic acid
