Calvin Cycle Uses ATP and

NADPH to convert CO2 to carbohydrates

2 spins around this cycle makes 1 molecule of glucose!

Photosynthesis - Two PartsLIGHT REACTIONS:

Make ATP and NADPH

CALVIN CYCLE:Uses the ATP

and NADPH to make

carbohydrates1. Light absorption (by plant pigments)2. Electron transport chain (making NADPH) 3. Chemiosmosis (making ATP)

4. Calvin Cycle (making carbohydrates)

What would happen to our world if plants went extinct?

1.Plants are autotrophs. They produce food for themselves and other organisms.

2.Plants use photosynthesis to regulate Earth’s environment.
