Detailed explanation-1: -Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. Times when your body’s oxygen level might drop include: During intense exercise.
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: -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-4: -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.
Detailed explanation-5: -During exercise, respiration goes into hyperdrive to provide enough energy demanded by our muscles. If not enough oxygen is available, the body instead produces ATP from glycogen through an anaerobic process, with another byproduct being lactic acid.
