1. Chapter 8
Energy From Sunlight

2. Photosynthesis / Cellular Respiration
Recycle a common set of chemicals:
Water
Carbon Dioxide
Oxygen
Glucose (Organic Compounds)

3. The Energy in Food ATP – Adenosine Triphosphate
main energy supply for cells

4. ATP can be recycled; Requires energy
ATP Cycle
ATP can be recycled; Requires energy

5. Visible Light (White Light)
ROYGBIV

6. Photosynthesis
The process by which plants and other producers convert the energy of sunlight into the energy stored in organic molecules (sugars).

7. Chloroplast
The organelle where photosynthesis takes place

8. Chloroplast
Stroma – thick fluid enclosed by inner membrane Thylakoids – disk shaped sacs in stroma

9. Photosynthesis

10. Photosynthesis Two Main Stage
Stage I Light Reaction (Thylakoid) IN: Light, Water OUT: Oxygen, ATP (energy), NADPH (electron carrier)

11. Photosynthesis
Stage II The Calvin Cycle (Stroma) IN: CO2, ATP and NADPH (both from the light reaction) OUT: SUGAR!!!!
