Aerobic metabolism is the way your body creates ATP, the basic currency of energy, through the conversion of carbohydrates, proteins (amino acids), and fats in the presence of oxygen.

Using the Krebs cycle (Also called as the Tricarboxylic Acid (TCA) cycle, or simply the Citric Acid Cycle), aerobic metabolism is an 8-step process that produces up to 38 ATP compared with just 2 for Anaerobic metabolism.

Aerobic metabolism is used for the sustained production of energy for endurance efforts.
