(I) The electron carriers of phosphorylation are located in the thylakoid.

(II) During phosphorylation, the chloroplast stroma becomes more acidic than the interior of thylakoid membrane.
(III) Protons diffuse through the protein channels which are synthetase molecules.

(IV) is formed from on the stroma side of the thylakoid in the chloroplast.
