Transcript

  • 1.  
  • 2. Biology I: Energy, Metabolism, and ATP
  • 3. Agenda – Mon. Oct. 10, 2011 Warm-Up (5 min): Lesson (15 min): Wrap-Up (10 min): Finish Projects/Missing Quizzes (20 min):
  • 4. Today’s Objectives
    • I will define: energy , thermodynamics , metabolism , photosynthesis , cellular respiration , and adenosine triphosphate (ATP) .
    • I will articulate the first and second laws of thermodynamics.
    • I will classify two types of metabolism.
  • 5. Warm-Up
    • Does available energy decrease or increase as you go up an energy pyramid?
    • Make a simple food chain using only words.
    • Label your organisms as producer, primary consumer, secondary consumer, tertiary consumer, or decomposer.
  • 6.
    • Energy is the ability to do work.
    How Do Organisms Obtain Energy? Cellular Energy
    • Thermodynamics is the study of the flow and transformation of energy in the universe.
    Chapter 8
  • 7. Laws of Thermodynamics
    • First law — energy cannot be created nor destroyed.
      • Derived from the law of conservation of energy .
    How Do Organisms Obtain Energy? Cellular Energy
    • Second law — energy cannot be converted without the loss of usable energy.
      • Example: When consumers convert chemical energy into kinetic energy, some energy is loss as heat to the environment but NOT destroyed.
    Chapter 8
  • 8. Metabolism – all of the chemical reactions in a cell How Do Organisms Obtain Energy? Cellular Energy
    • Photosynthesis — light energy from the Sun is converted to chemical energy for use by the cell
    • Cellular respiration — organic molecules are broken down to release energy for use by the cell
    Chapter 8
  • 9. ATP: The Unit of Cellular Energy How Do Organisms Obtain Energy? Cellular Energy Chapter 8
  • 10. ATP: The Unit of Cellular Energy
    • ATP releases energy when the bond between the second and third phosphate groups is broken , forming a molecule called adenosine diphosphate (ADP) and a free phosphate group.
    How Do Organisms Obtain Energy? Cellular Energy Chapter 8
  • 11. Wrap-Up
  • 12.
    • Energy cannot be converted or destroyed.
    • Energy can be converted and destroyed.
    • Energy can be converted but not destroyed.
    • Energy can be destroyed but not converted.
    Which statement describes the law of conservation of energy? Cellular Energy Wrap-Up (Oct. 10) Chapter 8
  • 13. Which law of thermodynamics explains why the ladybug receives the least amount of usable energy? Cellular Energy Wrap-Up (Oct. 10) Chapter 8
  • 14.
    • the first law of thermodynamics
    • the second law of thermodynamics
    Cellular Energy Wrap-Up (Oct. 10) Chapter 8
  • 15. True or False All of the energy from the food you eat comes from the sun. Cellular Energy Wrap-Up (Oct. 10) Chapter 8
  • 16.
    • It captures light energy from the sun.
    • It is produced in anabolic pathways.
    • It stores and releases chemical energy.
    Why is adenosine triphosphate (ATP) such an important biological molecule? Cellular Energy Wrap-Up (Oct. 10) Chapter 8
    • It converts mechanical energy to thermal
    energy.
  • 17. Look at the following figure. Which molecule is released when ATP becomes ADP? Cellular Energy
    • phosphate group
    • water molecule
    • ribose sugar
    • energy cells
    Wrap-Up (Oct. 10) Chapter 8
