Such a muscle cell will have to turn to lactic acid fermentation since it must have ATP to live and to work, but the lack of oxygen will stop the usual means of ATP production (aerobic respiration).
Work Step by Step
The way to get this answer is to first examine the state and purpose of the muscle cell. It lacks the normal fuel for work, and the normal way of generating that fuel is blocked. Thus, scan the chapter for other ways of making ATP (fermentation) and which kind is performed by muscles.
