PHOTOSYNTHESIS!

Warm up!• Sit where you can FOCUS best.

• What are the parts of ATP? (you can draw it out)• How is ATP used? (you can draw it out)• What are some similarities and differences between plant

and animals cells?• List 3 similarities• List 2 differences

• If you could learn anything about the world, what would it be?

Photosynthesis

Photosynthesis is taking light energy and converting it sugar.

Why Care?• http://www.pbs.org/wgbh/nova/tech/capturing-carbon.html• We can use photosynthesis to reduce carbon dioxide in the air!

Who Does Photosynthesis?• Plants, algae, etc.

Where does Photosynthesis Occur?• In the chloroplast

General Steps of Photosynthesis• General Equation for Photosynthesis

• General Steps of Photosynthesis1. Light Reaction

2. Calvin Cycle aka Dark Reaction aka Light Independent Reaction

Light ReactionThe light reaction turns light energy into chemical energy in the form of ATP and NADPH

The light reaction occurs in the thylakoid membrane in the chloroplasts.

Calvin Cycle• The Calvin Cycle (aka The Dark Reaction aka The Light

Independent Reaction) takes chemical energy and carbon dioxide to make sugar.

• The dark reaction occurs in the stroma of the chloroplasts
