Photosynthesis
Storyboard-Text
- What I need (or the reactants) is light energy, water, carbon dioxide and chlorophyll. If I have all these things, and I can continue through my process. I end up with (the products) glucose (sugar), oxygen and water.
- Hi! I'm Photosynthesis, and I'm going to tell you what I do. I capture light energy from the sun and convert it to chemical energy of food. I nourish almost all the living world directly or indirectly.
- Chlorophyll is the green pigment in the plant.
- Water
- Light
- Oxygen
- Carbon Dioxide
- There are two stages in which photosynthesis occurs. That's the Light Reactions and the Calvin Cycle.
- Light reactions are steps that convert energy from the sun to make ATP and NADPH. Those supply chemical energy and reducing power.
- The Calvin Cycle incorporates CO2 into organic molecules that are converted to sugar.
- The Light Reactions take place on thylakoids and the Calvin Cycle occurs in the stroma.
