3.  In the chloroplast

4.  Carbon dioxide  Water

5.  Oxygen  Glucose

6. Light reactions Dark reactions Take place in: Thylakoid membrane Produces: 2 ATP, NADPH, O 2 Takes place in: Stroma Produces: Glucose, ADP, NAPH +

7. Requires:  Light Uses:  Water (H 2 O) Produces:  ATP, NADPH, Oxygen

8. Animation  Light reaction Light reaction  Light reaction 2 Light reaction 2  Light reaction explained Light reaction explained

9. Uses: CO 2 ATP NADPH Produces: Sugars (GLUCOSE) ADP NADP +

10. ◦ Plants use the energy from ATP and NADPH to build high energy SUGARS (GLUCOSE) that can store energy for longer than a few minutes.

11.  The carbon and oxygen needed to build the sugars come from CO 2 in the atmosphere.

12.  The Calvin cycle uses CO 2, ATP and NADPH  and creates Sugar, ADP and NADP+

13.  Calvin Cycle Calvin Cycle
