Unformatted text preview: cell from a given amount of ATP i s smaller when [ATP]/[ADP] falls and greater when this ratio r ises. -30.5kJ/mol + (2.48 kJ/mol)(-7.8) = -50 kJ/mol -30.5kJ/mol + (2.48 kJ/mol)(-4.7) = -42 kJ/mol -30.5kJ/mol + (2.48 kJ/mol)(-2.8) = -38 kJ/mol -30.5kJ/mol + (2.48 kJ/mol)(-1.0) = -33 kJ/mol -30.5kJ/mol + (2.48 kJ/mol)(-3.0) = -38 kJ/mol 6. (15%) The standard reduction potential. The Eº of any redox pair is defined for the half-cell reaction: Oxidixing 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 conjugate pair has the greater tendency to lose electrons? Explain. The NAD+ & NADH pair will lost more electrons because the E' of NAD+/NADH (-0.0320 V) is more negative than the pyruvate/lactate (-0.185V), so pyruvate/lactate has a greater tendancy to accept electrons and is the stronger oxidizing system (b) Which is the stronger oxidizing agent? Explain. pyruvate/lactate is the stronger oxidizing agent because it is more likely to accept...
