A description particularly of the chemiosmotic aspect of the light reaction of photosynthesis.
Photophosphorylation is analgous and, indeed, probably homologous to oxidative phosphorylation. That is, the use of electron transport chains to generate a proton motive force which is then employed to drive the phosphorylation of ADP using an ATP synthase enzyme. The major difference is that with photophosphorylation it is photons rather than a chemical energy source that is giving rise to the energetic electrons being donated to the electron transfer chains.
