BiologyPhotosynthesisA2/A-levelEdexcel Created by: xcasey.janexCreated on: 13-10-16 11:23 What is the role of Chlorophyll Where chemical reactions take place 1 of 19 What is the Photosynthesis equation Carbon dioxide + Water Glucose + Oxygen 2 of 19 What is needed for photosynthesis to occur Sunlight, Water, Carbon dioxide, Chlorophyll 3 of 19 Definition of Oxidation Addition of oxygen and loss of electrons, loss of hydrogen and energy given out 4 of 19 Definition of Reduction Loss of oxygen, gains electrons and gains hydrogen 5 of 19 Where does Light-dependent take place Takes place in the Thylakoid Membranes of the chloroplast 6 of 19 What happens to electrons when light is absorbed Light energy excites electrons and they gain higher energy level to travel through transport chain 7 of 19 What does water under go to give an electron Photolysis 8 of 19 What happens at ATP synthase Protons move down the concentration gradient. ADP +PI ATP 9 of 19 What is the electron used for in PS1 Electron is used for NADP Reduced NADP (co-enzyme) 10 of 19 What does Cyclic Photophosphloration Only produces ATP 11 of 19 Why is it Cyclic Electron excites to higher energy level but is not passed on to NADP 12 of 19 What is the other name for Light independent reaction The Calvin Cycle 13 of 19 What combines to create an unstable 6C molecule CO2 and rubisco 14 of 19 What does unstable 6C molecule brakes down into 2 3C compounds 15 of 19 What is ATP & Reduced NADP used for in the Calvin Cycle and where does it come from ATP is used to covert GP into GALP and comes from the light dependent reaction 16 of 19 What does GALP form Useful organic compounds such as glucose, lipids 17 of 19 What is used to convert GALP RUBP ATP is used 18 of 19 What is needed for the calvin cycle to occur again 5C molecule 19 of 19
