Lack of oxygen in muscles often leads to cramps in the legs of sprinters. This is due to the conversion of pyruvate to:
(a) ethanol
(b) carbon dioxide
(c) acetic acid
(d) lactic acid

Question

Lack of oxygen in muscles often leads to cramps in the legs of sprinters. This is due to the conversion of pyruvate to:
(a)	ethanol
(b)	carbon dioxide
(c)	acetic acid
(d)	lactic acid

MyClass24 · Accepted Answer

lactic acid

Lack of oxygen in muscles causes accumulation of lactic acid, due to anaerobic respiration. Accumulation of lactic acid leads to cramps in the legs of sprinters.
