The overall process of photosynthesis produces sugars that store chemical energy. 6CO2 + 6H2O  C6H12O6 + 6O2.

KEY CONCEPT The overall process of photosynthesis produces sugars (glucose) that store chemical energy.

The Need for Energy  Energy is essential to life.  The molecule that stores energy is ATP or adenosine triphosphate.

PHOTOSYNTHESIS WHY IS THIS IMPORTANT?

Our planet runs on solar energy Provides us with all our food requirements and much of our fuel requirements global warming

Where Does Photosynthesis Happen? Photosynthesis happens in Chloroplasts Chlorophyll is the green pigment located within the chloroplasts

Overview of Photosynthesis Light-dependent reactions –Light energy is transferred to ATP and NADPH –Water molecules are split, releasing O 2 Light-independent reactions (Calvin Cycle) –Energy in ATP and NADPH drives synthesis of glucose and other carbohydrates from CO 2 and water
