Non-cyclic phosphorylation

• 1. Photon hits chlorophyll in PSII
• 2. Electrons get excited
• 3. electrons taken up by electron receptor and passed along an electron transport chain to PSI
• 4. energy is released, ATP is synthesised
• 5. photolysis

  light energy breaks apart bonds in water molecules forming hydrogen and hydroxide bonds

  electrons released replace lost electrons in PSII

  hydroxide ions react to form water and oxygen
• 6. photon hits chlorophyll in PSI
• 7. electrons get excited
• 8. NADP takes up H+ ions and form reduced NADP
