1. 6-2 Notes: Calvin Cycle

2. Calvin Cycle Series of reactions that produces C6H12O6 (glucose)
6CO2 + 6H2O → →→→→C6H12O6 (glucose)+ 6O2
Occurs in the stroma

3. Calvin Cycle
Reactants: CO2, and NADPH & ATP (from light rxn)

4. Calvin Cycle Reactants: CO2, and NADPH & ATP (from light rxn)
The energy in ATP is transferred into CO2 rearranging bonds to form C6H12O6 (glucose)
Product: Glucose

5. Calvin Cycle
CO2 is the carbon source
for C6H12O6 (glucose)

6. The Fate of Glucose Some will be used for energy
(broken down in mitochondria)
For growth and development

7. The Fate of Glucose
Some will be used for energy (broken down in mitochondria)
For growth and development
The unused (excess) will be stored as starch (ex: potatoes)

8. Photosynthesis and Global Warming
CO2 is a greenhouse gas (traps heat)

9. Photosynthesis and Global Warming
CO2 is a greenhouse gas (traps heat)
CO2 is currently being released faster than photosynthesis can remove it
Burning of fossils fuels

11. Photosynthesis and Global Warming
Deforestation: clearing of forests for farming and human settlements

12. Photosynthesis and Global Warming
25% of carbon dioxide added to the atmosphere comes from cutting and burning forests in the tropics.

13. Photosynthesis and Global Warming
25% of carbon dioxide added to the atmosphere comes from cutting and burning forests in the tropics.
Grasslands and crops
remove 30-60% less CO2
per acre than forests

14. Photosynthesis and Global Warming
Replanting helps: young trees have faster net photosynthetic rates than older trees.
