1. The Light Dependent Reaction

   • 1. PHOTOLYSIS
     • Water enters the thylakoid space from the water transport systems. The energy from the light breaks the covalent bonding within water and splits it into 2H atoms and 1O atom.
       • Light energy further splits the H atoms into 2H+ ions and 2e-.
         • The protons create a proton gradient across the membrane so the H+ can flow by chemiosmosis and drive ATP synthase.
