AUTOTROPHIC NUTRITION

PHOTOSYNTHESIS

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

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

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

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

2 REACTIONS AND THEIR GOALS THE OVERALL REACTION SUNLIGHT 6CO2 +12 H2O C6H12O6 + 602 + 6H2O ENZYMES 2 REACTIONS AND THEIR GOALS LIGHT REACTION: TO PRODUCE OXYGEN FROM WATER DARK REACTION: TO PRODUCE FOOD (C6H12O6) FROM CO2 AND HYDROGEN (H2)

6CO2 +12 H2O C6H12O6 + 602 + 6H2O O2 H2 H2O Sunlight Photolysis Enzymes, light O2 Sunlight Photolysis H2 To Dark Reaction LIGHT REACTION H2O ATP Grana ADP Energy P ADP + P

Reactions in between NADPH2 H2 H2 From Light Reaction NADP To Dark Reaction ENERGY

Phosphoglyceraldehyde 6CO2 +12 H2O C6H12O6 + 602 + 6H2O Enzymes, light H2O CO2 DARK REACTION Enzymes of Stroma C6H12O6 2 PGAL H2 Phosphoglyceraldehyde (3 carbon compound) Energy

Photosynthesis and Respiration are two equal and opposite reaction. To maintain a balance (HOMEOSTASIS) between the environment and the organisms that occupy it. Autotrophs (Plants) CO2 + H2O C6H12O6 + O2 + H2O Heterotrophs (Animals)
