Question

Why aerobic reaction burns more fat than anaerobic reaction?

There is an explanation. Can someone explain it?

Anaerobic exercise utilizes lactic acid fermentation to produce ATP. This process

only goes through the end of glycolysis, after which the pyruvate produced during

glycolysis is converted into lactic acid. As a result, no fat can be metabolized,

because fatty acids enter the metabolic cycle of the Krebs cycle. Additionally, the B-

oxidation process responsible for converting fatty acids into acetyl-CoA is oxygen

dependent.

Explanation / Answer

During anaerobic exercises (no much oxygen is consumed), body uses glycolysis (breakdown of glucose into pyruvate and acetic acid) to generate energy, which makes only 2ATP per one glucose molecule. The pyruvate generated is converted into lactic acid. So, during this process, no fats are recruited to generate energy. This is because beta oxidation of fats is an oxygen dependent process (means, cannot be carried out in the absence of oxygen). That's why the body cannot use anaerobic metabolic continuously for no more than 30 sec. to generate energy. After anaerobic exercise, we loss much glucose and becomes fatigue but does not loss any fat.
