Aerobic vs. Anaerobic Respiration: A comparison

*

Why oxygen?

Oxygen is the final electron acceptor at the finish of the electron transfer chain of aerobic respiration. In the absence of oxygen, only a few ATP are developed from glucose. In the presence of oxygen, many more ATP room made.

Advantages of Aerobic Respiration

A major advantage that aerobic respiration is the lot of energy it releases. Without oxygen, historicsweetsballroom.comlogy can break-up glucose into just 2 molecules that pyruvate. This releases only enough power to make 2 ATP molecules. Through oxygen, historicsweetsballroom.comlogy can malfunction glucose every the way to carbon dioxide. This releases enough energy to create up come 38 ATP molecules. Thus, aerobic respiration releases much much more energy than anaerobic respiration.

The lot of energy produced by aerobic respiration may explain why aerobic organisms concerned dominate life ~ above Earth. It may also explain just how organisms were able to become multicellular and also increase in size.


Advantages of Anaerobic Respiration

One benefit of anaerobic respiration is obvious. It allows organisms live in areas where over there is tiny or no oxygen. Such places encompass deep water, soil, and the digestive tracts of animals such as human beings (see Figure below).

Another advantage of anaerobic respiration is its speed. The produces ATP very quickly. Because that example, it lets your muscles get the energy they need for quick bursts that intense task (seeFigure below). Aerobic respiration, on the other hand, produce ATP much more slowly.
