AEROBIC & ANAEROBIC METABOLISM

AEROBIC METABOLISM

  -It's the way our body creates energy through burning carbohydrates, amino acids, and fats in the presence of oxygen.

  -This metabolism is used for the sustained production of energy for exercise and other body functions. 

ANAEROBIC METABOLISM

  -It's the creation of energy through the burning carbohydrates in the absence of oxygen. This occurs when your lungs can't put enough oxygen into the bloodstream to keep up with the demands of your muscles for energy.

   -It'sused for short bursts of activity, such as when you go for a sprint when running or cycling.

   -When there isn't enough oxygen in the bloodstream, glucose can't be fully broken down to carbon dioxide and water. Instead, lactid acid is produced, which can build up in the muscles and degrade muscle function.


Our body will often switch between aerobic and anaerobic metabolism during sports and exercise activities that require short bursts of sprints as well as sustained jogging, such as in soccer, tennis, and basketball.


CONFRONTATION

  -Anaerobic metabolism is not as efficient as aerobic metabolism. A molecule of glucose can only produce three ATP (what fuels the muscles)molecules under anaerobic metabolism, while it produces 39 with aerobic metabolism. 
  -Anaerobic metabolism can only use glucose and glycogen, while aerobic metabolism can also break down fats and protein.
