  1. what does light reaction harness energy from
    sun and the calvin cycle
  2. energy-storing process where light energy is captured and converted into chemical energy in the form of organic molecules such as glucose
    photosynthesis
  3. equation for photosynthesis
    6CO2 + 12H2O + sunlight->C6H12O6 + 6O2 + 6H2O
  4. name for the chemical rxns of photosynthesis
    light reactions
  5. in light reaction what are the photons absorbed by
    photosystem I and II
  6. what happens at the photosystems
    light energy excites electrons at the reaction center
  7. What do electrons do in the photosystems
    • transfer to primary electron acceptor
    • ->travel through electron transport chain
  8. what do electrons eventually do in the photosystems?
    reduce NADP+ to NADPH
  9. where do the protons go when ECT pumps them out?
    thylakoid lumen
  10. the proton gradient powers the production of ATP through what?
    chemiosmosis
  11. what are the NADPH and ATP required for?
    • fixing of CO2
    • generation of glucose in Calvin Cycle
  12. term for photosystems of the light rxns for the shape during the process
    z-scheme
  13. the electrons from water is boosted with energy by?
    sunlight
  14. summary of electron movement
    H20->PS II->ECT->PSI->ECT->NADPH
  15. who developed the first evidence of electron movement?
    Robert Hill in 1937
  16. How did Robert Hill study movement of electrons?
    • by adding a artificial electron acceptor to chloroplast
    • like DCIP
  17. summary of movement of electrons in the Hill rxn
    2H2O->PSII->ECT->DCIP
  18. What plant are we using to observe the chloroplast?
    spinach
