    ok im slightly confused by this. am i right that the electrons emitted from photosystem 1 go to the hydrogen ions from the photolysis of water? and it gets its replacement electrons from photosystem 2?

    Electrons from PSII ultimately go (via PSI) to the H+ ions from the photolysis of water. The H atoms produced are used to reduce (NADP+) to (NADPH + H+). The two electrons that were taken from PSII are replaced by electrons which also come from the photolysis of water. The oxygen released by the photolysis of water is release as O2 (a product of photosynthesis).
