Well, although water is used in Calvin cycle, its main role is to supply two missing electrones in P680. In that process it’s split into 2e-, 2H+ and an oxygen molecule that combine with another to form O2 molecule.
For the other things you will need to make some effort maybe to find something. I am 100% sure it’s in every biological textbook and academic physiology, biochemistry or cell structure book.
