\rarr

NADH E_o (volts) = - 0.32
Pyruvate^- + 2H⁺ + 2e^-

\rarr

lactate ^2- E_o(volts) = - 0.19
In a redox reaction involving NAD/NADH and pyruvate,_____________ will be the electron donor and ____________ will be the electron acceptor.

Quizplus · Accepted Answer

According to the given half reactions, NADH is the electron donor and pyruvate is the electron acceptor in the redox reaction involving NAD/NADH and pyruvate. Therefore, option B is the correct choice.

Consider the Following Two Half Reactions: NAD+ + H+ →\rarr→ NADH Eo (Volts)= - 0

Consider the Following Two Half Reactions: NAD⁺ + H⁺ $\rarr$ NADH E_o (Volts)= - 0
