What I Know About Aerobic and Anaerobic Respiration

After being introduced to studying a little on this topic, I became interested to find out more on aerobic and anaerobic respiration. First of all, I have learnt that both of the respiration processes are different in their own ways. In both processes, ATP, or adenosine triphosphate, is involved.
Aerobic Respiration
Aerobic respiration occurs in plants, and scientifically speaking, it is the release of energy from glucose or another organic substance in the presence of oxygen. During aerobic respiration, oxygen is required, and the process is divided into two processes: the Krebs cycle, and the Electron Transport Chain, which produces ATP. The molecules are reduced, receiving high energy electrons, thus representing energy available to do work.
Anaerobic Respiration
This process is very different from aerobic respiration.In anaerobic respiration, organisms produce usable energy in the form of ATP without the presence of oxygen. In other word, it is respiration without the need of oxygen. These organisms are usually bacteria or other micro-organisms which live in environments which lack the presence of oxygen. However, even though oxygen is not involved in this process, it is still a form of respiration, because all three basic steps of respiration are used- glycolysis, the citric acid cycle, and the respiratory chain.

These are the two different forms of respiration, and their differences can be seen from the points stated above.
