BiologyCellular processes and structureA2/A-levelAQA Created by: SamanthaCreated on: 04-01-13 18:25 Where does the light dependent stage of photosynthesis take place? In the thylakoid membranes of the chloroplast 1 of 19 What type of energy is used to make ATP? Light energy 2 of 19 How is ATP made? By adding an inorganic phosphate molecule (Pi) to an ADP molecule 3 of 19 What are the products of the light dependent stage? ATP and reduced NADP 4 of 19 Where are the products of the light dependent reaction used? In the light independent reaction 5 of 19 What is the ATP produced in the light dependent reaction used as? Energy and reduces NADP to form reduced NADP 6 of 19 What is the role of the reduced NADP in the light dependent reaction? To transfer a hydrogen molecule 7 of 19 What process occurs during the light dependent stage? Photolysis 8 of 19 What is photolysis? The use of light to break water 9 of 19 What is water split into during photolysis? Protons (H+), electrons (e-) and oxygen 10 of 19 What happens to the oxygen produced by the photolysis of water? It is released into the atmosphere 11 of 19 What are the electrons produced by photolysis used for? To replace excited electrons that are emitted from chlorophyll 12 of 19 What happens to the H+ produced by the photolysis of water? It goes back to the e- (after it has passed through electron carriers) to reduce NADP 13 of 19 Where does the light independent reaction take place? In the stroma of the chloroplast 14 of 19 What is the light independent reaction also known as? The Calvin Cycle 15 of 19 What process takes place in the Calvin Cycle? Carbon fixation 16 of 19 What is carbon fixation? Where carbon is 'fixed' into an organic molecule 17 of 19 What are the products of the light independent stage? Triose phosphate 18 of 19 What can triose phosphate be used for? It can be used to make glucose and other useful organic substances 19 of 19
