Photosynthesis Notes Chapter 10 Photosynthesis The conversion of solar energy into ATP ATP is later used to produce glucose from H20 and C02 Anatomy of Chloroplasts Mesophyll cells Double Membrane Stromafluid interior Thylakoid systems Thylakoid Membranes PSII and PSI Proteins Chlorophyll Pigment Molecules There are 2 different types of light reactions Light Dependent Reactions relays on light energy and Light Independent Reactions using what was produced from the dependent reactions to make glucose Light Dependent Reactions Thylakoid Membrane I Formation of ATP and NADP I Uses Light and H20 Light Independent Reactionstr0ma Formation of glucose Calvin Cycle PSII and PSI Uses C02 ATP and NADPH Generation of ATP 1 H ions flow down concentration gradient 2 Move across thylakoid membrane to the Stroma 3 Move through ATP Synthase 4 ATP formed In PSII and PSI they both trap pigments and release light energy to the reaction center Chlorophyll Remember PSII is first then PSI PSII Reaction Center uses energy to give off e These e are used to pump H into the Thylakoid interior These e can also be used to break H20 PSI e from PSII through the Electron Transport Chain are reenergized to be used again to trap more light energy e then pass through 2nOI transport system to make NADPH Calvin Cycle 1 weww C02 binds with Rubisco enzyme responsible for breakdown of C02 Becomes PCA 12 ccc which uses 12 ATP and 12 NADPH Becomes G3P 12 ccc G3P looses 2 ccc to make glucose The remaining 10 ccc uses 6 ATP to make RuBP to begin cycle again Different Plants and Photorespiration C3 plants 0 Use C02 or 02 o Binds with RuBP 0 Calvin Cycle 0 Forms PGA to make glucose 0 Happens in most plants C4 plants 0 C02 is taken into the Mesophall Cells 0 Becomes C4 to start Calvin Cycle in Bundle Cells 0 Forms glucose 0 Happens in Plants like Corn or Sugarcane CAM plants 0 C02 becomes C4 at night 0 During the day begins Calvin Cycle to make glucose 0 Adapt well in dry environments
