What is anaerobic breathing?

In biology, anaerobic respiration is a metabolic process to produce the cells with chemical energy without the use of oxygen. It is a type of cellular breathing, an essential part of metabolism and a source of all growth, reproduction and repair that occurs in the cells. Glycolysis, which converts sugar into energy molecules, is the main type of anaerobic pathway found in most organisms. Anaerobic metabolism facilitates important chemical exchange between organisms and the environment, such as a nitrogen cycle.

All living organisms use energy to power their growth and reproduction. Cell -breathing is a type of cellular metabolism that extracts biochemical energy from various nutritional chemicals and converts it into ATP, universal energy transfer molecule. Anaerobic breathing is a type of cellular breathing occurring in cells that do not use oxygen molecules in their metabolism. The primary chemical path of anaerobic breathing-besides the Extreme metallic e-bacteria-glycolysis that divides MOlekulu simple glucose sugar for two pyruvic acid molecules and produces two molecules in the process.

aerobic breathing - using oxygen - in most higher organisms is more common than anaerobic, which effectively rely on oxygen for breathing. It creates much more ATP - 38 molecules - than glycolysis, which provides only two. In the earliest periods of development of life on Earth, however, there was not enough oxygen in the atmosphere to metabolize the cells, so they rely on various other molecules to produce energy anaerobically. Primitive organisms, including the oldest surviving bacteria and creatures living in hot springs and on the bottom of the ocean, still rely on it; Many of them die if they are exposed to oxygen.

humans and other animals use aerobic anaerobic breathing. This is important during short explosions of muscle activity that drives movement using glycolysis and produceslactic acid. If this acid accumulates, muscle pain and convulsions will be the result of. Some yeasts include a special type of anaerobic breathing - fermentation - into their metabolism. Fermentation spends sugars and provides ethyl alcohol and some gases as a by -product; That is why bread is rising because biochemical processes in yeast are changing chemical reactions in the body.

elementary replacement of nitrogen, sulfur and carbon on the Earth's surface and in the atmosphere are moderated by anaerobic breathing. For example, proteins and other biologically basic compounds contain a large amount of nitrogen, which is released back to the atmosphere by bacterial anaerobic metabolism. When some bacteria metabolize fuels without oxygen, they also release methane gas. Although this function is useful in microbiology and kerosene industry, excess methane production is a problem, because it is like a lot of greenhouse gas, as well as carbon dioxide, associated with climate change.
