When light energy excites electrons in photosystem II, where do the electrons to replace them come from?. . A.ATP. B.photosystem I. C.the light energy. D.split water molecules.
2H₂O⇒4e⁻ + 4H⁺ using this equation the electrons replace the lost ones in chlorophyl photolysis occurs. photosystem II "splits" water To replace its lost electrons Produces oxygen 2 H2O 4 H 4 e- O2 This process is called oxygenic photosynthesis
