Question

6 multiple choice 10 points in glycolysis,______is oxidized and______is reduced. pyruvate nadh glucose nad+ glucose nadh pyruvate nad+

Explanation:

Glycolysis is the metabolic pathway that converts glucose into pyruvate. During glycolysis, glucose is oxidized (loses electrons/hydrogen). \(NAD^{+}\) acts as an electron/hydrogen acceptor. When \(NAD^{+}\) gains electrons/hydrogen, it is reduced to \(NADH\). Pyruvate is the end - product of glycolysis (not the starting material for oxidation in the context of the overall glycolysis reaction as a whole). \(NADH\) is the reduced form, so it cannot be the reduced species in the reaction (since it is already reduced).

Answer:

glucose \(NAD^{+}\) (the second option)
