The number of ATP molecules formed from 8 molecules of H2o due to noncyclic electron transport and subsequent photophosphorylation is
[Assume that quinone cycle facilitates the transfer 4H+ to the lumen of thylakoid membrane for every two electrons passing through electron transport system and one ATP is formed for every 3H+ moving down the proton gradient by the mediation of F0 - F1 ATPase]
