Anaerobic respiration

• Anaerobic respiration

  Respiration without oxygen
• Anaerobic respiration

  1. Glucose breakdown

  2. Incomplete

  3. End products: Animal cells - lactic acid, Plant cells and yeast - carbon dioxide and ethanol

  4. Relatively small amount of energy released from each glucose molecule
• Aerobic respiration

  Respiration with oxygen
• Aerobic respiration

  1. Glucose breakdown

  2. Complete

  3. End products: Carbon dioxide and water

  4. Relatively large amount of energy released from each glucose molecule
• Anaerobic respiration produces only 2 molecules of ATP, compared to 38 molecules of ATP produced by aerobic respiration
• Anaerobic respiration in muscles leads to a build-up of lactic acid, which needs to be oxidised to carbon dioxide and water later
• Vigorous exercise

  Generates an oxygen debt that needs to be repaid after the exercise stops
• A short intense burst of exercise such as sprinting will generate energy anaerobically, creating an oxygen deficit
• The word equation is Glucose ➡️ Latic acid + energy in the form of ATP
