- In an anaerobic environment, the pyruvate produced during glycolysis is reduced to lactic acid
- 2-hydroxypropanic (lactic) acid produced during heavy exercise lowers cellular pH. Lowering the pH can cause the denaturing of enzymes. This can impair muscle contractions, causing the possibility of cramps.
- When oxygen levels in the body increase again following intense exercise, muscle cells will go back to aerobic respiration.
