Anaerobic respiration: Learn the key differences between

Learn the key differences between aerobic and anaerobic respiration , the two types of cellular respiration that occur in living organisms. Find out how oxygen, glucose, and energy are involved in each process, and see examples of organisms that use them. Aerobic respiration takes place in the presence of oxygen and is the primary process through which cells produce energy. It involves the complete breakdown of glucose into carbon dioxide and water, releasing a large amount of energy (around 38 ATP molecules). This process mainly occurs in the mitochondria of cells. On the other hand, anaerobic respiration occurs in the absence of oxygen. Anaerobic Respiration Definition What is anaerobic respiration ? Anaerobic (cellular) respiration is a respiratory process that occurs in both prokaryotes and eukaryotes in which cells break down the sugar molecules to produce energy without the presence of oxygen. While fermentation involves only the glycolysis step, certain anaerobic respiration types make use of the electron transport chain system to pass the electrons to the final electron acceptor. Anaerobic respiration is the process of creating energy without the presence of oxygen. Sometimes the body cannot supply the muscles with the oxygen it needs to create energy, for example during intense exercise. Without the process of anaerobic respiration , there would be no energy supplied to muscles in these times of high demand.This article will consider the process of anaerobic respiration and its clinical significance.
