Describe the three types of energy balance in the body and what each one is used for.

Explanation:

Lactic Acid System

The lactic acid system, also called the anaerobic glycolysis system, produces energy from muscle glycogen -- the storage form of glucose. Glycolysis, or the breakdown of glycogen into glucose, can occur in the presence or absence of oxygen. When inadequate oxygen is available, the series of reactions that transforms glucose into ATP causes lactic acid to be produced -- in efforts to make more ATP. The lactic acid system fuels relatively short periods -- a few minutes -- of high-intensity muscle activity, but the accumulation of lactic acid can cause fatigue and a burning sensation in the muscles.
