Anaerobic respiration

• Anaerobic respiration


  Respiration without oxygen
• Anaerobic respiration in muscles


  Glucose → Lactic acid + energy in the form of ATP
• Glucose


  A simple sugar used by cells for respiration
• Lactic acid


  A toxic chemical produced during anaerobic respiration
• Oxidise


  Chemical substances are oxidised by the addition of oxygen, removal of hydrogen or the removal of electrons
• Oxygen debt


  The amount of extra oxygen required by the body for recovery after vigorous exercise
• Oxygen deficit


  The difference between the oxygen the body needs during the sudden sprint and what it actually managed to take in
• Short intense burst of exercise


  Generates energy anaerobically so an oxygen debt will be generated
• Differences between aerobic and anaerobic respiration


  • Oxygen needed/not needed
  • Glucose breakdown complete/incomplete
  • End products
  • Energy released relatively large/small amount
• Aerobic respiration produces 38 molecules of ATP, but anaerobic respiration produces only two molecules of ATP
• Anaerobic respiration produces 5% of the ATP produced by aerobic respiration
