Photons of light are absorbed by the chlorophyll and excite e-s (move to a higher E level by photoionisation) 2. Loss of e-s from PSII stimulates the photolysis of water (H2O -> H+ + e-s + O2) 3. e-s lost from chlorophyll pass along a series of e- carriers, redox reactions occur 4. E = released as e-s pass along E.T.C 5.
