6. What occurs in Photosystem II?

  • Light hits chloroplast, absorbed by P680, excites electron, water splits into H+ and E- and Oxygen via photolysis
  • Light hits chloroplast, absorbed by P800, excites electron, water splits into H+ and E- and Oxygen via photolysis
  • Light hits chloroplast, absorbed by P680, excites electron
  • Light hits chloroplast, absorbed by P680, excites electron, water splits into N and E- and Oxygen via photolysis
