Answer:

Explanation:

Fast-twitch muscle also uses glycolysis to produce energy, but it skips harvesting energy from pyruvate, a process that takes oxygen. Instead, pyruvate gets converted into a waste product, lactic acid, and released into the bloodstream

Answer: Lactic acid is produced in your muscles when you perform strenuous exercise. It’s produced mainly in muscle cells and red blood cells when the body breaks down carbohydrates for energy when oxygen levels are low. These levels decreases during intense exercise or when a person has an infection or disease.
