Light reaction Photosynthesis

1. 1. Photons (light energy) come into chloroplast (thylakoid)P

2. 2. Photons HIT a water molecule

3. 3. Oxygen (from water) leaves as a waste product.

4. 4. Hydrogen are stored onto NADP+ and makes NADPH.

5. 5. ATP is also produced.  

​Photon 

​H20

​Oxygen

​ATP

​H + NADP+ = NADPH
