Chemistry

NADH and FADH2 are often considered â€œenergy currencyâ€ incellular metabolism because they are generated
directly from Glycolysis and the TCA cycle. Using the followinghalf-cell potentials, calculate the Gibbs Free Energy
that can be derived from the oxidation of NADH and FADH2. Use theFaraday Constant at 96,500 J/V mol.
FAD + 2H+ +2 e- = FADH2 Eo = -0.219V
NAD+ + H+ + 2 e- = NADH Eo = -0.320V
a. 21.3 and 30.8 kJ/mol
b. -21.3 and -30.8 kJ/mol
c. 42.3 and 61.8 kJ/mol
d. -42.3 and -61.8 kJ/mol
