Photosystem – Non-cyclic Electron Flow in Light Dependent Reactions387159511874500_________________ excites photosystem (II). H2O splits into _______________________________In the thylakoidO2 is released by the plant2H+ help create a concentration gradient2 electrons ar passed through electron transportElectrons go to _________________________ then through b6-f complex to ______________________. The b6-f complex pumps H+ from the stroma into the thylakoid to generate a ___________________________________.________________________ in the PC get excited by photon hitting photosystem II.Electrons from PC get passed to _________________________________ and through NADP reductase enzyme which ___________________ NADP to NADPH.Build-up of __________in the ________________ causes a concentration gradient (chemiosmosis) where H+ will go through ATP synthase to produce ATP from ADP and PIPhotophosphorylation – Net Result of Light Dependent Reactions:Cyclic Electron FlowLight independent reactions require _______________________________________ - therefore more ATP needs to be made than NADPH….Cyclic photophosphorylation can occur to produce extra ATP.Electrons can flow in a cycle allowing for more ________________________________.Once electrons are accepted by Fd, they are cycled back _______________________________ and cause additional H+ to cross the membrane. With additional H+ on the thylakoid side of the membrane, ATP synthase makes more ATP.NADPH is not made because electrons were not passed to NADP reductase.The Calvin Cycleleft-408200The Calvin CycleOccurs in the ______________________ of the chloroplastTakes 3 CO2 and produces _________________________________________________________No ___________________________ is required for the Calvin Cycle to take place and it is therefore called __________________________________________.Steps in the Calvin CycleFixation of carbon dioxide3CO2 combines with ribulose bisphosphate (RuBP) to make 2 3-phosphogylcerate moleculesReduction of 3-phosphogylerate into glyceraldehyde-3-phosphate (G3P)uses ATP and NADPHproduct = G3PRegeneration of RuBP from G3PUses ATPThe Fate of G3P Net Equation for Calvin Cycle ................
