The phosphorylation of adp3− is given by: adp3−+h++hpo2−4→atp4−+h2o(l) . at t=310k the molar gibbs energy change for the phosphorylation of adp is δgrxn=32.0kj/mol . in the cell the phosphorylation of adp3− is coupled to the oxidation of glucose by the reaction c6h12o6+38adp3−+38h++38hpo2−4+6o2→3 8atp4−+44h2o+6co2. we define the efficiency of this coupling as the fraction of the molar gibbs energy change from oxidation of glucose that is diverted into adp phosphorylation. calculate the efficiency ϵ of this coupling.
