Presentation Transcript

  1. Enzyme Catalyzed Reactions Chemical Reactions Substrates  Products Reactants  Products

  2. Title Date U3-15

  3. Types of Reactions • Synthesis – small reactants  big products • Stores Energy • Digestion – big reactants  small products • Releases Energy

  4. Photosynthesis Harnessing Energy For All!

  5. photo – synthesis • What does photo mean? • light • What does synthesis mean? • Making big things from small things. • Put it together and you get things being made from light. • Where does the energy from the sun go? What is being made? • Into glucose.

  6. What is involved with photosynthesis?

  7. What are the reactants of photosynthesis? Carbon Dioxide (CO2) Water (H2O)

  8. What are the products of photosynthesis? Oxygen (O2) Glucose (C6H12O6)

  9. Lets Write the Reaction 2 Ways

  10. What kind of reaction is photosynthesis? • Synthesis or Digestion? • Is energy stored or released? Synthesis Stored

  11. What organelle does photosynthesis? • The Chloroplast

  12. Chlorophyll • Chlorophyll is a pigment that absorbs light. • Chlorophyll reflects green light.

  13. Photosynthesis • Plants are Autotrophs. Autotrophs harness energy from an abiotic source. • What source of energy do Autotrophs tap into? • The SUN! • Plants are Producers. Producers harness carbon from an abiotic source. • What source of carbon do Producers tap into? • Carbon Dioxide!

  14. FOOD Why is photosynthesis so important to all life on Earth? ? ? ? ? ?
