It is the site of light independent step of photosynthesis 1 of 24 What is the purpose of the Grana? Site of the light dependent of photosynthesis 2 of 24 What is the envelope made from? two layers of membrane contains ATP synthase 3 of 24 What is the first stage of the light independent stage? Carboxylation 4 of 24 What is carboxylation? CO2 is 'fixed' by RUBP 5 of 24 What is made? 2 molecules of GP 6 of 24 What is this step catalysed? by the enzyme RuBISCO 7 of 24 What is the next step? Reduction step 8 of 24 What happens in the reduction step? educed NADP is oxidised forming 2 GALP. 9 of 24 What is required in this step? ATP 10 of 24 What is the 3rd step? REgeneration 11 of 24 What happens in this step? 5/6 GALP molecules are converted back into RUBP 12 of 24 What is the equation to work out the Gross primary production? Net primary production / Respiration 13 of 24 What is GPP? the amount of glucose q plant generates through P/S 14 of 24 What is NPP? the balance of glucose a plant has left over to use for growth, NPP is proportional to biomass 15 of 24 What is the structure of an enzyme? Globular protein, active site and charged R groups outside molecule 16 of 24 What is the first stage of DNA profiling? multiplies copies of DNA made 17 of 24 What is used? Polymerase chain reaction 18 of 24 What are the 3 stages of Polymerase chain reaction? 1.90 degrees, denatured 2. 50 - 60 degrees, annealing of primers, 3. 70-80 degrees, extending 19 of 24 What is then used? restriction enzymes to produce DNA fragments 20 of 24 What is the next process called? gel electropherisis 21 of 24 Where is the DNA placed? on the gel 22 of 24 What is then passed through? electric current 23 of 24 What light is then used? UV 24 of 24
