Anaerobic Respiration


Anaerobic respiration occurs when there is not enough oxygen. In humans a

common situation is during exercise when the oxygen supply is less than the

demand from the cells. Therefore the cells have to use anaerobic respiration

to get the energy.  However you do not get the same products. Anaerobic

respiration produces a substance called lactic acid.

Anaerobic respiration can also be used to make alcohol. This reaction

occurs in microorganisms such as bacteria and yeast, which use glucose to

form carbon dioxide and ethanol.  This process is known as fermentation.

Oxygen debt


The process of anaerobic respiration can lead to oxygen debt. Oxygen debt

is when the amount of oxygen entering the body is less than required by the

muscles. Therefore your heart, lungs, and blood cannot keep up with the

demand.

 

Therefore after you stop doing the exercise you will keep breathing heavily

to ensure that enough oxygen enters the system to enter the muscles and

to ensure all the harmful lactate and carbon dioxide.
