Oxygen is the final electron agree at the end of the electron move chain the aerobic respiration. In the lack of oxygen, only a few ATP are produced from glucose. In the presence of oxygen, many much more ATP space made.

Advantages the Aerobic Respiration
A major advantage that aerobic respiration is the amount of energy it releases. Without oxygen, ptcouncil.netlogy can split glucose right into just two molecules that pyruvate. This releases only enough power to make 2 ATP molecules. Through oxygen, ptcouncil.netlogy can failure glucose every the means to carbon dioxide. This release enough power to create up come 38 ATP molecules. Thus, aerobic respiration releases much an ext energy than anaerobic respiration.
The quantity of energy created by aerobic respiration may describe why aerobic organisms came to dominate life on Earth. The may also explain just how organisms were able to become multicellular and increase in size.
Advantages that Anaerobic Respiration
One advantage of anaerobic respiration is obvious. It lets organisms live in places where over there is tiny or no oxygen. Such places incorporate deep water, soil, and the cradle tracts of animals such as humans (see Figure below).
E. Coli bacteria are anaerobic bacteria that live in the human being digestive tract.

Another benefit of anaerobic respiration is that is speed. The produces ATP an extremely quickly. Because that example, it allows your muscles obtain the energy they require for short bursts the intense activity (seeFigure below). Aerobic respiration, ~ above the other hand, to produce ATP much more slowly.
