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.

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
