Aerobic anaerobic respiration

  1. 1. Aerobic/Anaerobic Respiration Harsimran
  2. 2. - The Marathon - <ul><li>If somebody challenged you to a run a race, how should you prepare to win? </li></ul><ul><ul><ul><li>Practice </li></ul></ul></ul><ul><ul><ul><li>Eat the right foods </li></ul></ul></ul><ul><ul><ul><li>Drink the right liquids </li></ul></ul></ul>
  3. 3. All living organisms break down sugars to get energy. In humans this breakdown usually occurs with oxygen.
  4. 4. Aim: To understand how Aerobic and Anaerobic Respiration Occurs
  5. 5. What is Aerobic Respiration? <ul><li>The breaking down of sugar to produce energy where oxygen is present. </li></ul>Glucose + Oxygen  Carbon Dioxide + Water+ Energy
  6. 6. When We Exercise… <ul><li>After two minutes of exercise, the body responds by supplying working muscles with oxygen. </li></ul><ul><li>When oxygen is present, glucose can be completely broken down into carbon dioxide and water </li></ul>
  7. 7. Anaerobic Respiration refers to the oxidation of molecules in the absence of oxygen to produce energy It is also known As Fermentation
  8. 8. <ul><li>In Muscle Cells - During extraneous activities, the oxygen in the muscle tissue is decreased to an extent that aerobic respiration does not occur at a sufficient rate. Hence, there is a buildup of lactic acid and your muscles get tired </li></ul><ul><li>2. In Yeast - The fermentation end product is ethyl alcohol, and CO 2 </li></ul>What happens when fermentation occurs?
  9. 9. Energy + Glucose Ethanol + Carbon Dioxide + Energy Chemical Formula for Anaerobic Respiration
