Equation
3
Where does photosynthesis take place?

• In the chloroplast

4
What are the reactants?

• Carbon dioxide
• Water

5
What are the products?

• Oxygen
• Glucose

6
Two Phases of Photosynthesis
Dark reactions
Light reactions
Take place in Thylakoid membrane Produces ATP
, NADPH, O2
Takes place in Stroma Produces Glucose, ADP,
NAPH

Light Dependent Reactions

• Requires
• Light
• Uses
• Water (H2O)
• Produces
• ATP, NADPH, Oxygen

9
Dark Reactions (Calvin Cycle)
Uses CO2 ATP NADPH
Produces Sugars (GLUCOSE) ADP NADP
10
Dark Reactions

• Plants use the energy from ATP and NADPH to build
  high energy SUGARS (GLUCOSE) that can store
  energy for longer than a few minutes.

11
Dark Reaction

• The carbon and oxygen needed to build the sugars
  come from CO2 in the atmosphere.

12
Dark Reaction

• The Calvin cycle uses CO2, ATP and NADPH
• and creates Sugar, ADP and NADP
