Aerobic respirtation is the process by which glucose and oxygen go to form carbon dioxide and water. The reaction occurs in the mitochondria. The process is needed to release energy. The chemical equation of the it is: C6H12O6 + 6O2 -> 6CO2 + 6H2O.
Anaerobic repiration is similar however it doesn't require oxygen and only relases a smaller burst of energy. The equation is as follows: Glucose -> lactic acid (C6H12O6 -> 2C3H12O3). It should be said that lactic acid is toxic and therefore needs to be oxidised. The reaction occurs in the cytoplasm of the cell.
