Document Summary

The electrons in water replace the ones left. Main goals = create proto gradient - to drive atp synthase . Atp synthase = same one in cell resp too. Big e- carrier = nadp+ = reduced to nadph. Photosystem 1= helps electron flow to atp generation and also creating nadph. Clicker question => if holes taken out of leaf and put in water = leaf disc will float. Photosynthesis: because air in plant struc keeping leaves floating. 2nd clicker => light one go through photosynthesis so will float and the ones in the dark don"t so they sink. Atp synthase = same structure as in respiration and uses gradient. Proton motive force = energy in gradient. Energy movement in photo = initial excitement from photon of light -> lose energy - >once energy lost = electron absorbs photon to be excited again -> goes to final electron acceptor (nadph.
