2. AUTOTROPHIC NUTRITION

3. PHOTOSYNTHESIS

4. Nutrition Autotrophic nutrition: (Plants) Organisms that can synthesize organic compounds from inorganic compounds. (Make sugar from water) Organisms that can not synthesize organic compounds from inorganic. Heterotrophic Nutrition: (Animals)

5. Photosynthesis The making of food from Sunlight!!. Sun

6. Where does Photosynthesis take place? Plants?  Where?  How? What gives plants this ability?  Why?

7. The Chloroplast 2 Essential regions where photosynthesis takes place. GRANA: Stacked membranes. Where the LIGHT REACTION takes place. STROMA: Fluid filled with enzymes. Where the DARK REACTION takes place Stroma Grana

8. 6CO 2 +12 H 2 O C 6 H 12 O 6 + 60 2 + 6H 2 O SUNLIGHT 2 REACTIONS AND THEIR GOALS LIGHT REACTION: DARK REACTION: TO PRODUCE OXYGEN FROM WATER TO PRODUCE FOOD (C 6 H 12 O 6 ) FROM CO 2 AND HYDROGEN (H 2 ) THE OVERALL REACTION ENZYMES

9. Sunlight H2OH2O Photolysis O2O2 H2H2 6CO 2 +12 H 2 O C 6 H 12 O 6 + 60 2 + 6H 2 O Grana ADP P ATP Energy ADP + P Enzymes, light LIGHT REACTION To Dark Reaction

10. H2H2 NADP NADPH 2 ENERGY From Light Reaction H2H2 To Dark Reaction Reactions in between

11. H2H2 H2OH2O C 6 H 12 O 6 6CO 2 +12 H 2 O C 6 H 12 O 6 + 60 2 + 6H 2 O Enzymes, light DARK REACTION CO 2 Energy Enzymes of Stroma 2 PGAL Phosphoglyceraldehyde (3 carbon compound)

12. Photosynthesis and Respiration are two equal and opposite reaction. To maintain a balance (HOMEOSTASIS) between the environment and the organisms that occupy it. Heterotrophs (Animals) CO 2 + H 2 O Autotrophs (Plants) C 6 H 12 O 6 + O 2 + H 2 O
