Photosynthesis(light-independent stage) 0.0 / 5 ? BiologyHuman, animal and plant physiologyA2/A-levelCCEA Created by: Football03Created on: 09-03-22 10:05 Where does the light independent stage occur? In the storma of the chloroplast 1 of 18 What products are carried from the light-dependent stage? ATP & NADPH 2 of 18 What happens CO2 in this stage? CO2 is fixed into organic compounds 3 of 18 CO2 combines with RuBP(5C) and is catalysed by what enzyme? Rubisco enzyme 4 of 18 What does this reaction form? 2 molecules of glycerine phosphate(GP) -3 CARBON MOLECULE 5 of 18 What is used to reduce GP? ATP & NADPH to reduce GP to TP 6 of 18 What does NAPH produce ? Reducing power 7 of 18 What does ATP produce? Energy 8 of 18 How many molecules of TP are produced in the recycling of Ribulose bisphosphate(5C)? 5 molecules of TP 9 of 18 What is used to provide the phosphate and energy to make RuBP? ATP 10 of 18 What is 1/6 of the TP made used to produce? Other organic molecules (glucose/sucrose/glycerol/fatty acids/amino acids) 11 of 18 Does the light-independent stage need light? No (but needs products ATP AND NADPH for Calvin cycle) 12 of 18 What happens when light is removed in the light-dependent reaction? Reaction stops=no light independent stage 13 of 18 What happens if GP cannot be converted to TP? A build up of GP and a reduction in RuBP 14 of 18 What happens if co2 is no longer available in the reaction ? CO2 cannot be 'fixed' and combine with RuBP,GP then cannot be formed 15 of 18 What happens to the RuBP when no co2 is fixed? RuBP builds up and GP already in system gets converted to TP leading to its rapid fall 16 of 18 What happens as the Calvin cycle stops? Each concentration levels off 17 of 18 What is Calvins experiment also referred to? 'lollipop' experiment 18 of 18
