Oxygen is the final electron acceptor at the end of the electron transfer chain the aerobic respiration. In the absence of oxygen, just a few ATP are produced from glucose. In the presence of oxygen, many more ATP space made.
You are watching: What is the main advantage of aerobic respiration
Advantages of Aerobic Respiration
A major advantage of aerobic respiration is the lot of energy it releases. Without oxygen, organisms can separation glucose right into just 2 molecules that pyruvate. This releases just enough energy to make 2 ATP molecules. With oxygen, yellowcomic.comlogy can malfunction glucose all the way to carbon dioxide. This releases enough power to produce up come 38 ATP molecules. Thus, aerobic respiration publication much an ext energy 보다 anaerobic respiration.
The amount of energy produced by aerobic respiration may explain why aerobic organisms involved dominate life top top Earth. That may also explain exactly how organisms were able to become multicellular and increase in size.
Advantages that Anaerobic Respiration
One advantage of anaerobic respiration is obvious. It allows organisms live in places where there is little or no oxygen. Together places include deep water, soil, and the cradle tracts of pets such as humans (see Figure below).
E. Coli bacteria space anaerobic bacteria the live in the person digestive tract.

Another benefit of anaerobic respiration is that is speed. That produces ATP really quickly. For example, it allows your muscles gain the energy they need for short bursts the intense activity (seeFigure below). Aerobic respiration, ~ above the various other hand, to produce ATP more slowly.
