A Correct answer
Explanation

Photosynthetic phosphorylation or photophosphorylation is the process of phosphate group transfer into ADP to synthesize energy rich ATP molecule making use of light, as external energy source. Down flow of protons from high to low concentration along H+ conc. gradient through ATPase complex, provides the energy that allows an ATP synthase enzyme, to produce ATP from ADP + Pi
