Muscle cells use lactic acid fermentation to produce less CO_2 produce more ATP than in respiration generate NAD+ so that glycolysis can continue in the absence of oxygen. allow an animal to survive for long periods of time in the absence of oxygen produce ATP in the presence of oxygen Solution Muscle cells use lactic acid fermentation to generate NAD+ so that glycolysis can continue in the absence of oxygen because once there comes a situation of oxygen supply the body usually exasperates and makes up the pyruvate thus removing the lactic acid and going back to producing pyruvate..
