PHOTOSYNTHESIS
WHY IS THIS IMPORTANT?
Our planet runs on solar energy
Provides us with all our food requirements and much of our fuel requirements

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 O2
• Light-independent reactions (Calvin Cycle)– Energy in ATP and NADPH drives synthesis of
glucose and other carbohydrates from CO2 and water
