PHOTOLYSIS OF WATER

• WHY DOES PHOTOLYSIS OF WATER OCCUR?

  chlorophyll molecule must replace lost electrons
• EQUATION FOR PHOTOLYSIS OF WATER?

  2H2O -> 4H+ + 4e- + O2
• WHAT HAPPENS AFTER PROTONS PASS OUT OF THYLAKOID SPACE VIA ATP SYNTHASE?

  • taken up by NADP
  • NADP becomes reduced (NADPH) after it takes up the electrons
  • NADPH enters next stage with the electrons
• WHAT IS NADPH?

  an electron carrier
• HOW DO PROTONS PASS OUT OF THE THYLAKOID SPACE?

  ATP synthase
• WHAT ARE THE USES OF THE OXYGEN PRODUCED?

  respiration/ diffuses out of leaf as waste
