Detailed explanation-1: -Lactic acid is fuel for your cells during intense exercise. It’s created when your body breaks down glucose and other carbohydrates. It’s a common myth that muscle soreness you feel after exercise is caused by lactic acid trapped in your cells.

Detailed explanation-2: -The lactic acid that is produced as a waste product of anaerobic respiration in humans is usually broken down once more oxygen is available. The process of lactic acid breakdown requires oxygen and produces the same products as aerobic respiration, carbon dioxide and water.

Detailed explanation-3: -When we do heavy exercise, sufficient oxygen is not present in the muscle cells for oxidation, so the muscle cells undergo anaerobic respiration giving out lactic acid as a by-product. Accumulation of lactic acid in the muscles cause muscular cramps. On further availability of oxygen, this lactic acid is broken down.

Detailed explanation-4: -Final answer: Sometimes when we do heavy exercise, anaerobic respiration takes place in our muscle cells. Lactic acid is produced during this process.

Detailed explanation-5: -When your body runs out of oxygen, or your other systems can’t deliver oxygen to your muscles quickly enough, your muscles convert the available glucose into lactic acid instead.
