1. Photosynthesis Cornell Note Hints When drawing diagrams put labels on left side and drawing on right Text in Bold – Put on the left side Text next to or below bold – put on right side EX: –ELECTRON (ENERGY) CARRIERS: Molecules that transport energy from one molecule to another Electron Carriers Molecules move NRG from one mole. to another

5. Remember…Chloroplasts in Elodea

6. Look Inside a Chloroplast *Draw a chloroplast and Label the Thylakoids and Stroma (liquid portion of chloroplast)

7. ELECTRON (ENERGY) CARRIERS: Molecules that transport energy from one molecule to another Example: ATP –ADP adds a phosphate group to become ATP, a high energy bond. NADPH –NADP+ picks up a H+ and stores energy as NADPH.

8. Photosynthesis is actually a TWO STAGE Process 1)Light energy from the sun is converted into energy carriers ATP and NADPH and Oxygen is released. Note: Water makes O2 2) The energy from ATP and NADPH is used to make SUGARS from Carbon Dioxide. Stage B Light Dependant Reactions Stage A

10. Step A: Light-Dependent Reaction Occurs in the Thylakoid Membrane. Light Energy from the Sun: –Splits water producing Oxygen Gas –Converts ADP into ATP and NADP+ into NADPH. Light dependant reaction animation

11. Step B: Light-Independent Reaction (Calvin Cycle) Occurs in the Stroma ATP and NADPH from the Light Reaction are used to produce high-energy sugars such as glucose. Animation of light reaction "feeding" light indepentant reaction
