In the stroma of the chloroplast 1 of 17 The reactions use the products of which stage? The light-dependent stage 2 of 17 What are these products? ATP and reduced NADP 3 of 17 What does ATP act as? A source of energy 4 of 17 What does the reduced NADP act as? The source of the reducing power to reduce CO2 and synthesise heroes sugar 5 of 17 First thing that happens in the light-independent stage? A five-carbon acceptor molecule, ribulose bisphosphate combines with carbon dioxide 6 of 17 What does this form? An unstable six-carbon compound 7 of 17 What happens to this compound? It immediately splits into two molecules of three-carbon compound 8 of 17 What are these called? Glycerate-3-phosphate 9 of 17 What then happens to the glycerate-3-phosphate? It is phosphorylated by ATP and then reduced by reduced NADP 10 of 17 To form what? Triose phosphate 11 of 17 Some of this three-carbon sugar can be built into what? Glucose phosphate 12 of 17 And then into starch by what process? Condensation 13 of 17 In order for the cycle to continue most of the triose phosphate formed enters a series of reactions driven by what? ATP 14 of 17 Which result in the regeneration of what? Ribulose bisphosphate 15 of 17 The NADP is reformed and goes where? Back into the light-dependent reaction 16 of 17 Why? So it can be reduced again 17 of 17
