10. Standard Reduction Potentials. The standard reduction potential, E'º, of any redox pair is defined for the half-cell reaction: Oxidizing agent + n electrons ? reducing agent The E'º values for the NAD+/NADH and pyruvate/lactate conjugate 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) What is the standard free-energy change (?G'º) for the conversion of pyruvate to lactate? d) What is the equilibrium constant (K'eq) for this reaction?

The standard reduction potentials (E°) for the following half reactions are given: α-KGA + CO2 + 2H+ + 2e- → Isocitrate NAD+ + H+ + 2e- → NADH E° = -0.380 V E° = -0.320 V Which of the following is true if the full reaction is: Isocitrate + NAD+ → α-KGA + CO2 + NADH + H+ Isocitrate has a greater affinity for electrons than does NAD+. α-KGA is reduced compared to isocitrate. NAD+ is the electron acceptor, Isocitrate is the electron donor, and the reaction as written above is spontaneous at standard conditions. NADH is the oxidized form of NAD+. All of the above are true.

The standard reduction potentials for two biologically relevant redox reactions are as follows: NAD+ + H+ + 2e- ↔ NADH (E°' = -0.315 V) FAD + 2H+ + 2e- ↔ FADH2 (E°' = -0.219 V) What is the standard reduction potential change (ΔE°') for an overall reaction in which NADH is oxidized and the electrons released are used to reduce FAD? 1. -0.534 V 2. -0.096 V 3. +0.096 V 4. +0.534 V
