Pyruvate + CoA + NAD⁺ → ____ + CO₂ + ____ A) oxaloacetate; ATP B) malonyl CoA; NADH + H⁺ C) methylmalonyl CoA; biotin D) acetyl CoA; NADH + H⁺ E) succinyl CoA; NAD⁺

Question

Quizplus · Accepted Answer

The reaction is describing the conversion of pyruvate to acetyl CoA, which is catalyzed by the enzyme pyruvate dehydrogenase. The products of this reaction are acetyl CoA and NADH + H+ (the reduced form of NAD+). CO₂ in the reaction equation is not a real chemical species and is likely an error in formatting.

Pyruvate + CoA + NAD+ → ____ + CO2

Pyruvate + CoA + NAD⁺ → ____ + CO₂
