During gentle or moderate exercise, the products of cellular respiration of glucose are carbon dioxide and water (CO2 + H2O), just as in other cells.
But if the exercise is vigorous, the muscle cells can switch to anaerobic cellular respiration (fermentation), in which case they convert each molecule of glucose into two of lactic acid.
Later, most of the lactic acid is converted back to glucose.
During exercise muscle cells use oxygen.
The ending product of anaerobic respiration in muscle cells is lactic acid.
The substance that becomes an end product of respiration in muscle cells is latic acid. This will happen commonly at the end of a strenuous exercise.
Fermentation in muscle cells produces lactic acid. This happens when you have overworked your muscles, which can happen during exercise.
It oocurs in muscle cells during heavy exercise. :]

Muscle cells are produced during development in the embryo from stem cells called myoblasts. Muscle growth can also occur through exercise or injury, where satellite cells are activated to differentiate into new muscle cells.
Blood carries glucose and oxygen to muscle cells. Muscles require more of these during exercise, and so the heart pumps harder and faster.
During heavy exercise, the build-up of lactic acid in muscle cells can lead to muscle fatigue, cramping, and discomfort. This accumulation occurs when the body produces lactic acid faster than it can be metabolized, leading to a decrease in pH levels in the muscles, which can impair muscle function.
Exercise causes your muscle cells to widen and grow so that that muscle becomes bigger and stronger.
Lactic acid is produced during vigorous exercise when the supply of oxygen is limited. It is formed as a byproduct of anaerobic metabolism in muscle cells.
