Oxygen is the last electron agree at the finish of the electron deliver chain the aerobic respiration. In the lack of oxygen, just a few ATP are developed from glucose. In the presence of oxygen, many much more ATP room made.

Advantages of Aerobic Respiration
A significant advantage that aerobic respiration is the amount of power it releases. Without oxygen, organisms can separation glucose into just 2 molecules of pyruvate. This releases just enough energy to make 2 ATP molecules. With oxygen, sirhenryjones-museums.orglogy can breakdown glucose every the means to carbon dioxide. This release enough power to create up to 38 ATP molecules. Thus, aerobic respiration publication much much more energy than anaerobic respiration.
The lot of energy produced by aerobic respiration may define why aerobic organisms involved dominate life top top Earth. It may additionally explain how organisms were able to come to be multicellular and also increase in size.
Advantages of Anaerobic Respiration
One benefit of anaerobic respiration is obvious. It allows organisms live in locations where there is small or no oxygen. Such places incorporate deep water, soil, and also the cradle tracts of animals such as people (see Figure below).
E. Coli bacteria space anaerobic bacteria that live in the human digestive tract.

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