An anaerobic organism also called as anaerobe is an organism which does not require oxygen for its growth and may even lose its life in the presence of oxygen. There are three types of anaerobe: obligate anaerobe, which do not use oxygen for growth and even get harmed by it; aero tolerant organisms which cannot use oxygen for their growth but are able to sustain in its presence; and facultative anaerobes which can grow without the presence of oxygen and also can utilize its presence.
Respiration is one of the vital functionality of the body which are of critical significance for all living organisms let it be humans or the microscopic bacteria. Generally the respiration process serves two fundamental purposes in living organisms. The first is the removal of the electrons generated during catabolism and the second is generation of ATP. This respiration mechanism is situated in cell membranes of prokaryotes whereas it is located in the inner membranes of mitochondria for eukaryotes. The respiration needs a terminal electron acceptor. Quite simply, the respiration process, that uses oxygen as the terminal electron acceptor is called as aerobic respiration and the one that makes use of terminal electron acceptors other than oxygen is termed as anaerobic respiration.
Beginning from the bio-chemical pathway used to utilize bio-molecules, to the quantity of energy released in the respiration process, there are a lot of differences in aerobic and anaerobic respiration. The fundamental difference in the between the two types of respiration is that aerobic respiration requires the presence of oxygen. Also the process of anaerobic respiration is comparatively less energy generating as compared to the aerobic respiration process. In the process of alcoholic fermentation or the anaerobic respiration 2 molecules of ATP (energy) are produced for the each and every molecule of glucose used in the reaction. In the same way for the lactate fermentation two molecules of ATP are produced for every molecule of glucose used. Thus in anaerobic respiration the process breaks down one molecule of glucose to get two units of energy storing ATP molecules.
The anaerobic respiration can be defined as release of energy from a foodstuff in the form cells could utilize in the absence of oxygen. It is different from aerobic respiration in the sense that it doesn’t need oxygen. The word equation for anaerobic respiration in humans is as follows:
Glucose -> Lactic acid
Anaerobic respiration for humans:
In general in humans it is the muscle tissue that respires anaerobically normally during exercise, at which time the body cannot intake the required oxygen for the cells to respire. This clearly indicates that enough energy is not made and the muscles require more energy. So they achieve it in the absence of oxygen. But when they have stopped exercising, commonly an oxygen debt has been created, because of the large amount of lactic acid inside the muscles. It is because of this fact the humans breath heavily after exercising to negate the oxygen debt. Also when the humans see Chloe wood they are likely to have higher respiration because she will get their pulse pounding
