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?
A. The mitochondria can use the oxygen generated as a waste product during lactic acid fermentation to increase their output of ATP
B. When pyruvate is transformed into lactic acid, four more ATP molecules are produced that can power muscle movement while NAD is regenerated
C. For every glucose molecule that enters glycolysis, the cell generates, without oxygen, two ATP molecules that can keep the muscles moving.
D. 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.

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.

For every glucose molecule that enters glycolysis, the cell generates, without oxygen, two ATP molecules that can keep the muscles moving.

Generally,Glycolysis,  takes place in the cytosol  of cells with or without oxygen.Therefore it continuous mechanism should be in place during anaerobic respiration for supply of 2ATPs from the Net of 4 ATPs when pyruvate is formed, to ensure sustenance of energy.

Therefore,in this athlete, it is imperative to ensure continuous mechanisms of Glycolysis by constant availability of Co-enzyme NAD+ which must be reduced so that electrons can be available for the substrate phosphorylation steps for generation of pyruvate and ATPs.

Thus  as the lactic acid is formed from the pyruvate,it is easily removed from the body as wastes, instead of retaining by the muscles cells. The lack of oxygen ensure supply of  of 2ATPs for sustaining the athletes in the  anaerobic condition.

answer; /// i believe the correct answer is (reactants);

it is either c or d and i know for sure it is not a or b
