7. In glycolysis, the NADH formed in the glyceraldehyde 3-phosphate dehydrogenase reaction in vigorously contracting muscle must be reoxidized to NAD+ if glycolysis is to continue. The most important reaction involved in the reoxidation of NADH is:
(A) dihydroxyacetone phosphate=＞ glycerol 3-phosphate.
(B) pyruvate=＞lactate.
(C) glucose 6-phosphate=＞ fructose 6-phosphate.
(D) isocitrate=＞α-ketoglutarate.
(E) oxaloacetate=＞malate.
