Aerobic anaerobic respiration

  1. 1. Aerobic/Anaerobic Respiration By : farouk jaarah
  2. 2. - The Marathon -If somebody challenged you to arun a race, how should you prepareto win?
  3. 3. 1. Practice2. Eat the right foods3. Drink the right liquids
  4. 4. All living organismsbreak down sugars to getenergy. In humans thisbreakdown usuallyoccurs with oxygen.
  5. 5. Aim:To understandhow Aerobicand AnaerobicRespirationOccurs
  6. 6. What is Aerobic Respiration?The breaking down of sugar to produceenergy where oxygen is present. C 6 H 12 O6 + 6O2 Enzymes → 6CO2 + 6 H 2 O + 36 ATP   Glucose + Oxygen  Carbon Dioxide + Water+ Energy
  7. 7. When We Exercise…After two minutes of exercise, the body respondsby supplying working muscles with oxygen.When oxygen is present, glucose can becompletely broken down into carbon dioxide andwater
  8. 8. Anaerobic Respiration refers tothe oxidation of molecules in the absence of oxygen to produce energy It is also known As Fermentation
  9. 9. What happens whenfermentation occurs? 1.In Muscle Cells- During intensive activities, the oxygen in the muscle tissue is decreased to an extent that aerobic respiration does not occur at a sufficient rate. so, there is a buildup of lactic acid and your muscles get tired. Equation for anaerobic respiration in your muscles: C6H12O6 (Glucose) -> 2C3H6O3 (Lactic Acid) + Small amount of energy
  10. 10. 2. In Yeast- The fermentation end product is ethyl alcohol, and CO2
  11. 11. Chemical Formula for Anaerobic Respiration in yeastEnergy + Glucose  → Ethanol + Carbon Dioxide + Energy Yeast
  12. 12. Lab ExperimentCarbon dioxide can be tested using lime water Calcium hydroxide, Ca(OH)2.
  13. 13. So Who gives more energy? Aerobic or Anaerobic respiration ? Hint: Go back to the formula
