1. Photosynthesis Part 2 Light Independent Reaction

2. Remember ATP fuels all reactions that require energy
Building glucose molecules will require ATP as a source of energy
Other molecules needed are
CO2 from the atmosphere
NADPH (Electron carrier from light reaction)

3. Review and Preview

4. Light Independent Reaction Calvin Cycle
Four things happen during the cycle
1. Carbon dioxide incorporated into existing molecules 2. Carbon compounds gain electrons from NADPH
3. Glucose is made
4. Ribulose bisphosphate remade so cycle can continue

5. LIR or Calvin Cycle Carbon dioxide combined with RuBP LR LR LR
Using left over carbon and other atoms to remake RUBP
Electrons from NADPH given to other molecules
½ of a glucose molecule

6. Photosynthesis What can glucose be used for?
Raw materials for building other molecules.
Energy source to make ATP and drive endothermic reactions!
