26. Standard Reduction Potentials The standard reduc- tion potential, E”, of any redox pair is defined for the half-cell reaction: Oxidizing agent + n electrons – reducing agent The E’ values for the NAD+/NADH and pyruvate/lactate con- jugate redox pairs are -0.32 V and -0.19 V, respectively. (a) Which redox pair has the greater tendency to lose electrons? Explain. (b) Which pair is the stronger oxidizing agent? Explain. (C) Beginning with 1 M concentrations of each reactant and product at pH 7 and 25 °C, in which direction will the fol- lowing reaction proceed? Pyruvate + NADH + H P lactate + NAD+ (d) What is the standard free-energy change (AG) for the conversion of pyruvate to lactate? (e) What is the equilibrium constant (K) for this reaction? ishers – ISBN 9781319140149
