What is the reduction potential for the overall reaction?

Pyruvate + NADH + H+ --🡪 Lactate + NAD+


The half cell reaction ( with their standard reduction potentials ) are

Pyruvate + 2H+ + 2e- 🡪 Lactate (-0.19V)

NAD+ + H+ +2e- 🡪 NADH (-0.32V)

A) + 0.00V

B) + 0.03 V

C) + 0.13 V

D) +0.22 V

E) +0.15 V



Answer: C) + 0.13 V
