1. Photosynthesis I pp

2. sunlight
6CO2 + 6H2O  6O2 + C6H12O6

3. OVERVIEW OF PHOTOSYNTHESIS

4. PHOTOSYNTHESIS OCCURS IN TWO PARTS
LIGHT REACTIONS:
Make energy in the form of ATP and NADPH
CALVIN CYCLE:
Uses the ATP and NADPH to make carbohydrates

5. Chloroplasts
Chloroplasts contain granum which are stacks of thylakoids
Stroma is the solution surrounding the granum

6. Light and Pigments
Plant cells contain chloroplasts and the pigments are in the thylakoid membrane

7. Light Absorption
Clusters of pigments called photosystems (I and II) in the thylakoid membrane absorb light energy

8. Electron Transport Chain (E.T.C.)
Energy excites electrons from water which will transport (travel) down chain to pump H+ and make NADPH

9. Making Energy
NADPH
2 e-+ NADP+ + H+  NADPH

10. ATP
H+ build up on one side and then move through ATP synthase to make ATP
ADP + Pi  ATP
