  • Takes place in cells, more specifically mitochondria The raw materials are glucose and oxygen (the products from photosynthesis) Show them how formula is reversed. (You could make them tell you the products and reactants (raw materials))
  • Starts with glucose. Make sure to explain that ATP is used to start reaction. Glucose is broken down in half, hydrogens are broken off (energy is produced) and glucose is turned into pyruvic acid. The type of respiration that occurs depends on the presence of oxygen.
  • With oxygen. Pyruvic acid goes into Kreb’s cycle.
  • Have students write down their observations and conclusions on notebook paper and discuss with class.

    1. 1. Respiration PPT TEACHER NOTES <ul><li>This PPT was revised June 24, 2008 </li></ul><ul><li>There is a notes handout for this PPT. </li></ul>
    2. 2. Respiration To Breathe or Not to Breathe?
    3. 3. Respiration <ul><li>Respiration is the breakdown of food (glucose) to release energy. </li></ul><ul><li>Where does this take place? </li></ul><ul><li>Enzymes (catalyst) are special proteins that control the process of respiration. </li></ul>mitochondria
    4. 4. Cellular Respiration Glucose (C 6 H 12 O 6 ) Glycolysis ATP (no O 2 present) Fermentation Anaerobic (O 2 present) Oxidative Respiration Aerobic ATP Step One Step Two depends on whether Oxygen is present or not ATP activation energy to start the breakdown of glucose
    5. 5. Oxidative Respiration <ul><li>Aerobic Respiration </li></ul><ul><li>OXYGEN is present </li></ul>CO 2 H 2 O O 2 Oxidative Respiration Aerobic (O 2 present) 36 ATP Step Two (if oxygen is present)
    6. 6. FERMENTATION <ul><li>This is anaerobic respiration. </li></ul><ul><li>NO oxygen present </li></ul>Alcohol Fermentation EX: yeast ethyl alcohol + carbon dioxide Lactic Acid Fermentation lactic acid EX: muscles Step Two (if NO oxygen is present) Fermentation Anaerobic (no O 2 present) Fermentation Total ATP 2 ATP
    7. 7. Respiration Formulas <ul><li>AEROBIC RESPIRATION </li></ul><ul><li>OXIDATIVE Cellular Respiration </li></ul><ul><li> C 6 H 12 O 6 + O 2  CO 2 + H 2 O + 36 ATP </li></ul><ul><li>glucose + oxygen  carbon dioxide + water + 36 ATP </li></ul>
    8. 8. Respiration Formulas <ul><li>ANAEROBIC RESPIRATION </li></ul><ul><li>ALCOHOL Fermentation </li></ul><ul><li> C 6 H 12 O 6  C 2 H 6 O + CO 2 + 2 ATP </li></ul><ul><li>glucose  ethyl alcohol + carbon dioxide + 2 ATP </li></ul>

    10. 10. TRY THIS! <ul><li>Explain what was happening in this experiment. </li></ul>
    11. 11. Cycle of Energy in Life Process: Photosynthesis Organism: Plant Place Occurs: Chloroplast Glucose and O 2 Process: Respiration Organism: ALL Place occurs: Mitochondria CO 2 and H 2 O ATP
