4. Photosynthesis H2OH2OH2OH2O CO 2 O2O2O2O2 C 6 H 12 O 6 Light Reaction Dark Reaction Light is Adsorbed ByChlorophyll Which splits water Chloroplast ATP and NADPH 2 ADPNADP Calvin Cycle Energy Used Energy and is recycled. + +

5. Light Dependent Reaction Needs: –Light –Water –ADP –NADP –Pigments –Thylakoid membranes of the chloroplast Products –ATP –NADPH –oxygen

6. The Process Chlorophyll and other pigments take in light and H2O. They strip off the protons and release Oxygen. The H+ (protons) are used to turn ADP into ATP. The electrons are used to turn NADP into NADPH

8. Light Independent Reactions Process –C o2 enters the stomates of the leaf and the stroma of the chloroplast –It binds with RuBP using Rubisco enzyme to make PGAL. –Energy comes from ATP and NADPH –PGAL combines with more carbon to make sugar

9. Calvin Cycle/Light Independent Needs –NADPH –ATP –CO2 –Stroma of chloroplast Product –Glucose and other organic compounds
