PSI and PSII, produces ATP and NADPH.
Photons excite electrons in PSII, electrons escape chlorophyll and enter the electron transport chain - these electrons are replaced into chlorophyll by photolysis.
Electrons passed along electron transport chain, this releases energy which is used to pump protons into the thylakoid space.
Electrons enter PSI, ferredoxin then accepts these electrons and passes them to NADP in the stroma.
Protons diffuse out of the thylakoid space, through ATPsynthase causing ATP to be made.
H+ combines with electrons and NADP to from NADPH.
