    First oxygen is not produced in the process of photosynthesis, it is leaving the process as an irrelevant/unimportant byproduct.

    Water is split in 2 H+ ions and an 1/2 O2 molecule by photolysis, that is to say by the influence of light. It is an oxidation in photosynthesis to get H+ions free for ATP synthase. ATP synthase is a membrane protein which is crossed by the H+ ion as energy supplier for making ADP to ATP.
