Question
Cytochrome, a complicated molecule that we will represent
as CyFe2+, reacts with the air we breathe to supply energy
required to synthesize adenosine triphosphate (ATP). The
body uses ATP as an energy source to drive other reactions. At pH 7.0 the following reduction potentials
pertain to this oxidation of CyFe2+:
O2(g) + 4 H+(aq) + 4 e----->2 H2O(l) E°red = +0.82 V
CyFe3+(aq) + e- ----->CyFe2+(aq) E°red = +0.22 V
(a) What is ΔG for the oxidation of CyFe2+ by air? (b) If the
synthesis of 1.00 mol of ATP from adenosine diphosphate
(ADP) requires a ΔG of 37.7 kJ, how many moles of ATP are
synthesized per mole of O2?
