Thylakoids and Photosynthesis Version en ligne Review of structures and locations of light dependent reactions par Kirk Villanueva 1 Inside the chloroplast hydrogen ions are diffused to this space after moving through ATP synthase. Also the site of the Calvin Cycle 2 location of photosystem 2,1 electron transport chain and ATP Synthase 3 shaped like a flat disk for increased surface area. These are the site of the light dependent reactions 4 location of photolysis, High concentration of H+ ions 5 Photosystem 2, electrons from photolysis move through this structure. 6 Electrons move through these proteins release small amounts of energy and move H+ ions to the lumen 7 this is where electrons are re-energized for the second time 8 Charged H+ move to the stroma through this enzyme, making ATP via chemiomosis 9 Where ATP is phosphorylated to ADP
