Anaerobic Metabolism: Basic Principles and Implications for Living Organisms

Anaerobic metabolism is a type of energy metabolism in which the final electron acceptor in the system of redox reactions is not oxygen, but other substances. This process is of great importance for living organisms, since under some conditions anaerobic metabolism may be the only source of energy.

Basic principles of anaerobic metabolism

Anaerobic metabolism occurs in the absence or deficiency of oxygen. In this case, substances such as nitrates, sulfates, carbonates, ferrites and others can act as the final electron acceptor. In this case, electrons are transferred from donor molecules to acceptors, which is accompanied by the release of energy.

Anaerobic metabolism occurs in various conditions, for example, in the depths of the oceans, soil, inside animals and plants. In the process of anaerobic metabolism, oxidation products, such as nitrites or methane, can be used as a source of energy for other organisms.

Significance for living organisms

Anaerobic metabolism is of great importance for living organisms, since it can provide their energy needs in conditions where there is little or no oxygen. For example, anaerobic metabolism is the main source of energy for bacteria living in the depths of the oceans, where there is no light and oxygen. Anaerobic metabolism also plays an important role in soil, where it helps restore nutrients and maintain biodiversity.

In addition, anaerobic metabolism is used industrially to produce a variety of products, such as beer, wine, cheese and yeast. In medicine, anaerobic metabolism is used to diagnose and treat infections caused by anaerobic bacteria.

Conclusion

Thus, anaerobic metabolism is an important process for living organisms and is of great importance both in nature and in industry and medicine. Understanding the basic principles of anaerobic metabolism allows us to better understand the functioning of living systems and use it in various fields of science and technology.

Anaerobic metabolism

Anaerobic metabolism or respiratory respiration is a form of metabolic respiration in which oxygen within the body is not used. The use of energy in anaerobic metabolism can lead to the accumulation of significant amounts of biomass even when sufficient oxygen is available to the cells, for example in medicine and industry. Anaerobic respiration has become very popular in astrobiology because many other living systems do not have access to oxygen. Important organs that use anaerobic energy include the muscles, liver, heart and pancreas. In bacteria, the process also starts when calcium chloride is added upon exiting the stationary growth phase. In contrast, the formation of organic matter requires oxygen as the final energy acceptor, and this process is usually called aerobic metabolism; it is more characteristic of higher organisms such as animals, plants and bacteria, especially those that decompose organic waste.

Almost all eukaryotic cells secrete an enzyme called glucose-6-phosphatase to break down glucose into lactic acid vinegar. This enzyme is not associated with any specialized structures other than bacteria. In prokaryotes, this cleavage occurs by binding,
