When a person is sprinting, the person's muscle cells will begin using anaerobic respiration in addition to keeping the mitochondria respiring aerobically as much as the oxygen supply will allow. what benefits do muscle cells gain from anaerobic respiration in this situation? when pyruvate is transformed into lactic acid, four more atp molecules are produced that can power muscle movement while nad+ is regenerated. the oxygen generated as a waste product during lactic acid fermentation can be used by the mitochondria to increase their output of atp . adding electrons from nadh to pyruvate regenerates nad+ , so that glycolysis can continue, and produces lactic acid, a waste product that can diffuse out of the cell. without using oxygen, the cell generates two atp molecules that can keep the muscles moving for every glucose molecule that enters glycolysis.
