(b) Calculate the biological standard potential E* for the reduction of the biomolecule NAD+NADH in aqueous solution. You can assume [NAD] and [NADH+] are 1 M under these conditions.to
_______ V (c) The pyruvate ion is formed during the metabolism of glucose in the body. During exercise, the pyruvate ion is converted to lactate ion in the body by coupling to the half-reaction for NADH given in part (b). For the half-reaction, pyruvate(aq) + 2 H3O+(aq) + 2 e–!lactate(aq) + 2 H2O(l) the biological standard potential E* = –0.190 V. Write the cell reaction for the spontaneous reaction that occurs between these two biological couples and calculate "E* and "G* for the overall reaction.
