How many ATP are formed in light reaction from 8 water molecules?

by Jawad Mirza

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 this mediation of Fo - F, ATPase.
