(a) Write out the two reductive half reactions and indicate the E ̊' for each half reaction. Write out the full balanced reaction for the pyruvate to lactate rxn and indicate the ∆E ̊' for the reaction. (b) What is the free energy change under standard state conditions for thisreaction? Which direction is spontaneous?(c) Assume that in skeletal muscle cells the ratio of [NAD+] to [NADH] is 100, and that the[pyruvate] = 0.40 mM and [lactate] = 4.0 mM. What is the free energy change (∆G')for the conversion of pyruvate to lactate? Indicate the direction in which the reactionis spontaneous under these cellular conditions.arrow_forwardWhy did the authors worry about the temperature-dependent solubility of the carriers in thebilayer?
