question 107

Multiple Choice

During strenuous exercise, the NADH formed in the glyceraldehyde 3-phosphate dehydrogenase reaction in skeletal 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 \(\rightarrow\) glycerol 3-phosphate.
• B) glucose 6-phosphate \(\rightarrow\) fructose 6-phosphate.
• C) isocitrate \(\rightarrow\) \(\alpha\)-ketoglutarate.
• D) oxaloacetate \(\rightarrow\) malate.
• E) pyruvate \(\rightarrow\) lactate.
