Aerobic anaerobic respiration Presentation Transcript

  • 1. Aerobic/Anaerobic Respiration By : farouk jaarah
  • 2. - The Marathon -If somebody challenged you to arun a race, how should you prepareto win?
  • 3. 1. Practice2. Eat the right foods3. Drink the right liquids
  • 4. All living organismsbreak down sugars to getenergy. In humans thisbreakdown usuallyoccurs with oxygen.
  • 5. Aim:To understandhow Aerobicand AnaerobicRespirationOccurs
  • 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. 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. Anaerobic Respiration refers tothe oxidation of molecules in the absence of oxygen to produce energy It is also known As Fermentation
  • 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. 2. In Yeast- The fermentation end product is ethyl alcohol, and CO2
  • 11. Chemical Formula for Anaerobic Respiration in yeastEnergy + Glucose  → Ethanol + Carbon Dioxide + Energy Yeast
  • 12. Lab ExperimentCarbon dioxide can be tested using lime water Calcium hydroxide, Ca(OH)2.
  • 13. So Who gives more energy? Aerobic or Anaerobic respiration ? Hint: Go back to the formula
