1. Photosynthesis Part 2

2. 2 Phases of Photosynthesis
Light Dependent Reactions (Light Reactions)
*Happen in the thylakoid membrane
2. Light Independent Reactions (Dark Reactions)
(Calvin Cycle)
*Happen in the stroma

3. PHASE 2: Light Independent Reactions (Dark Reactions)(The Calvin Cycle)

5. These Reactions are Light-Independent
No sunlight is needed to power these reactions
Instead, ATP and NADPH provide the energy to make these reactions happen
The ATP and NADPH were made in the 1st phase of photosynthesis
No need for me here!

6. Reactants & Products
Carbon Dioxide is the reactant for these chemical reactions
Sugars are the products of these reactions
Plants use these sugars as a source of energy or as building blocks for complex carbohydrates

7. Important Enzyme
Rubisco – an enzyme that converts inorganic CO2 into organic molecules to be used by the cell
It is one of the MOST important biological enzymes

This VIDEO CLIP explains this cycle really well, but in more detail than you need to memorize

10. Light
6CO2 + 6H2O  C6H12O6 + 6O2
