Biology 11/4 Photosynthesis - light reactions: thylakoid - dark reactions: stroma electron transport chain: generates ATP chemiosmosis: electrons transferred ATP synthesized in stroma cyclic electron flow generates in which of the following? - ATP (electron transport chain) Calcin cycle - is similar to the citric acid cycle - occurs in the stroma - dark reactions/light – independent the calvin cycle uses ATP and NADPH to convert CO2 to sugar. Phase 1: carbon fixation (atmosphere carbon converted to some molecule) Phase II: reduction Phase III: regeneration of the CO2 acceptor RuBP: ribulose biphosophate: takes up carbon dioxide 6 ATP molecules taking up, to for 1 biphosglycerate reduced by NADPH adds its H to molecule to form glceradehydrate 3 phosphate makes glucose 3 Co2 molecules are fixed. 2 molecules of 3 carbon sugars 6 moleucuel is what we want. Start with 3 3 CO2 enters form add CO2 using ribulose three 6 carbon compound (unstable) 5 required to get ribulose biphosphate 1 used to form ribulose
