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.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
