Photosynthesis light dependent reaction

  1. 1. Two metabolic pathways LIGHT DEPENDENT LIGHT INDEPENDENT 16 ADP + 16Pi 16 ATP 12 NADP + 12H 12 NADPH12 H2O 24 H+ + 6O2
  2. 2. LIGHT DEPENDENT LIGHT INDEPENDENTIN: THYLAKOID STROMAUSES: WATER, LIGHT CO2, ATP, NADPHPRODUCES: HIGH ENERGY COMPOUNDS GLUCOSE
  3. 3. LIGHT DEPENDENT REACTIONS1. OCCURS PHOTOSYSTEMS = EMBEDDED IN THYLAKOID MEMBRANE2. CHLOROPHYLL KEY LIGHT CAPTURING MOLECULE ABSORBS LIGHT IN WAVELENGTHS OF RED, BLUE, VIOLET3. ACCESSORY PIGMENTS CAROTENOIDS AND PHYCOCYANINS4. PHOTOSYSTEMS – TWO DIFFERENT ONES a. Types PHOTOSYSTEM I PHOTOSYSTEM II
  4. 4. GENERAL ABOUT PHOTOSYSTEMS1. THEY ARE EACH A LIGHT HARVESTING COMPLEX2. GROUP OF MOLECULES (PROTEINS, CHLOROPHYLL, ACCESSORY PIGMENTS, e- CARRIER MOLECULES) THAT WORK TOGETHER TO HARVEST LIGHT INTO HIGH ENERGY COMPOUNDS3. STRUCTURE - 2 PARTS • LIGHT HARVESTING COMPLEX = 300 CHLOROPHYLL & ACCESSORY • e- TRANSPORT CHAIN = SERIES OF e- CARRIER MOLECULES IN MEMBRANE
