what is the usual fate of muscle glycogen
65% of lactic acid is converted to carbon dioxide and water, 20% into glycogen, 10% into Protein and 5% into glucose. It has been estimated that about 50% of the lactate produced during intensive exercise is used by muscles to form glycogen which acts as a metabolic fuel to sustain exercise.he breakdown of glucose or glycogen produces lactate and hydrogen ions (H+) - for each lactate molecule, one hydrogen ion is formed. The presence of hydrogen ions, not lactate, makes the muscle acidic that will eventually halt muscle function.
