I need some help in biology

[5489]

Explain the oxygen debt and it's relation to lactic acid build up as we over-excersize. How do we over come or correct both conditions?

could someone help me out with this question?

Working muscle uses ATP so fast, the only way for the cells to provide the necessary ATP that quickly is through glycolosis (breakdown of glucose). Since oxygen cannot reach the muscles quickly enough, your muscles go through anaerobic metabolism of glucose. The byproduct of anaerobic glycolosis is lactic acid/lactate. This buildup of lactic acid is what causes the soreness and burning in your muscles. Your body corrects this by eventually converting the lactic acid to pyruvate where it is shipped to the liver via the bloodstream to undergo oxidative phosphorylation.

I'm taking the biochemistry and molecular biology GRE subject test next month. I need the practice.
