reaction produces O2 gas and converts ADP to ATP and NADP+ to NADPH. First‚ pigments in Photosystem II absorb light‚ which is then absorbed by electrons‚ which are then passed along the Electron Transport Chain. Chlorophyll loses an electron‚ but interestingly‚ those missing electrons are replaced through enzymes in the thylakoid membrane‚ which divide H20. Secondly‚ electrons move through the Electron
