Aerobic respiration

Aerobic respiration is used when the body is continuing with activity for a long period of time and the energy to do so is produced with oxygen.

Equation

GLUCOSE + OXYGEN = CARBON DIOXIDE + WATER + ENERGY




Anaerboic respiration

Anaerboic respiration is used when physical activity is carried out without the use of oxygen. This can be only used in short burst and for short periods.


Equation

GLUCOSE = LACTIC ACID + ENERGY




Oxygen Debt

Because the glucose can only be partly broken down in the abscence of oxygen, LACTIC ACID is produced together witha much smaller amount of energy.

Build up of Lactic Acid causes acute fatigue and results in OXYGEN DEBT, wich must be repaid by continued deep breathing after exercise.
