Anaerobic Respiration



  The release of energy from glucose without using oxygen.

  Glucose à lactic acid + energy


·  Useful for when oxygen cannot be delivered fast enough


·  Releases less energy than aerobic respiration

·  Lactic acid is not removed from the body and must be broken down after exercise


·  Anyone who exercises hard will find their breathing and heart rate take a while to return to normal when exercise has ended

·  This is known as excess post-exercise oxygen consumption
