What Is The Role Of Nitrogen In The Human Body – Nitrogen is denoted by the symbol N. It is abundant in the environment, but humans cannot use it directly from the air or soil, but convert it into usable form from green plants and microbes. But the question arises, why nitrogen is important for humans and how they use it etc. are discussed in this article.

The symbol for nitrogen is N. It is necessary for the survival of plants and animals. It is one of the building blocks of life. It makes up 80% of our atmosphere. It is used to produce amino acids in our body, which in turn make proteins. It is also needed to make the nucleic acids that make up DNA and RNA. Humans and other species on earth require nitrogen in a “fixed” reactive form. Do you know what reactive nitrogen is used for? It is necessary for the food production process. Before 1900, we had access to using natural nitrogen to process food like manure. But after the invention of an industrial process known as the Haber-Bosch process, reactive nitrogen can be fixed to help process food. How do we get nitrogen into our body? We know that nitrogen makes up a large part of the Earth’s atmosphere. Humans cannot use nitrogen through respiration, but can absorb through consumption of plants or animals that have consumed nitrogen-rich vegetation. The air we breathe consists of about 78% nitrogen, so it is clear that it enters our body with each breath. This nitrogen helps in the synthesis of protein, amino acids that affect growth, hormones, brain function and the immune system. Is nitrogenous drink dangerous for health. Why does our body need nitrogen? As mentioned above, a person needs amino acids, and for this nitrogen is an important source, which further helps to synthesize human proteins. The process of metabolism in our body depends on enzymes, which include various types of proteins. DNA nucleic acid makes up your genes, while RNA is involved in protein synthesis, which requires nitrogen. We all know that without DNA we would not be alive. The human body needs nitrogen for full digestion of food and growth. This is very important for the development of the human fetus. Cell replacement, tissue repair all require nitrogen to produce new cells. To make some other types of compounds that are not proteins, nitrogen is used like heme in hemoglobin, which carries oxygen in red blood cells. So we learn that nitrogen plays a crucial role in our life. It helps in protein synthesis. Our body excretes ammonia, turning it into urea, which is excreted by the kidneys in the form of urine. In this way, nitrogen is returned to the environment. “General Sciences” Complete study material

The nitrogen cycle is important because nitrogen is an essential nutrient for sustaining life on Earth. Nitrogen is a major component of amino acids, which are the building blocks of proteins, and nucleic acids, which are the building blocks of genetic material (RNA and DNA). When other resources such as light and water are abundant, ecosystem productivity and biomass are often limited by the amount of available nitrogen. This is the main reason why nitrogen is an important part of fertilizers used to improve soil quality for agricultural activities.

The nitrogen cycle is an important part of how the Earth system works. Click on the image to the left to open the Understanding Global Change Infographic. Find the nitrogen cycle icon and identify other processes and phenomena in the Earth system that cause or are affected by changes in the nitrogen cycle.

Nitrogen cycles in both abiotic and biotic parts of the Earth system. The largest reservoir of nitrogen is in the atmosphere, mainly in the form of nitrogen (N

). Nitrogen gas makes up 78% of the air we breathe. Most nitrogen enters ecosystems through certain types of bacteria in the soil and plant roots, which convert nitrogen gas into ammonia (NH

Sustainable And Profitable Nitrogen Management

). This process is called nitrogen fixation. A very small amount of nitrogen is fixed by lightning, interacting with air. After nitrogen fixation, other types of bacteria convert ammonia into nitrate (NO

), which can then be used by other bacteria and plants. Consumers (herbivores and carnivores) obtain nitrogen compounds from the plants and animals they eat. Nitrogen is returned to the soil when organisms excrete waste or die and are decomposed by bacteria and fungi. Nitrogen is released back into the atmosphere by bacteria that get their energy by breaking down nitrates and nitrites into nitrogen (also called denitrification).

Nitrogen levels can vary significantly in aquatic and terrestrial habitats and can be affected by a variety of human activities and environmental phenomena, including:

The Earth system model below includes some of the processes and phenomena associated with the nitrogen cycle. These processes occur at different speeds and on different spatial and temporal scales. For example, nitrogen fixation by bacteria occurs at small spatial scales, but human use of fertilizers can affect entire ecosystems. Can you think of additional cause-and-effect relationships between parts of the nitrogen cycle and other processes in the Earth system?

Nitrogen is one of the elements most likely to limit plant growth. Like carbon, nitrogen has its own biogeochemical cycle, circulating in the atmosphere, lithosphere, and hydrosphere (Figure 5). Unlike carbon, which is stored mainly in sedimentary rocks, most nitrogen is found in the atmosphere as an inorganic compound (N

). It is the predominant atmospheric gas, making up about 79 percent of the atmosphere’s volume. Plants, however, cannot use nitrogen in its gaseous form and are able to assimilate it only after it has been converted into ammonia (NH

). This reduction process, called nitrogen fixation, is a chemical reaction in which electrons are captured from another molecule. A small amount of nitrogen is fixed by lightning, but most of the nitrogen extracted from the atmosphere is removed by nitrogen-fixing bacteria and cyanobacteria (formerly called blue-green algae).

Some species of nitrogen-fixing bacteria can coexist (symbiotically) closely with legumes and other plants, providing the plants with the nitrogen they need (Figure 6). In this symbiotic association, the bacteria are enclosed in nodules that grow on the roots of plants, through which nitrogen is obtained that has been fixed by the resident bacteria. Cyanobacteria have developed similar relationships with various life forms such as liverworts, hornworts, cycads, and at least one genus of flowering plants (

Other microorganisms perform important tasks that drive the nitrogen cycle. Although plants can absorb ammonia as well as nitrate, most soil ammonia is converted to nitrite (NOT

), and then into nitrates by some aerobic bacteria through the oxidative process of nitrification. Once nitrogen has been taken up by plants, it can be converted into organic forms such as amino acids and proteins. Animals can only use organic nitrogen that they obtain by consuming plants or other animals. When these organisms die, certain microbes, such as detritivores, can participate in the breakdown of organic nitrogen into ammonia (ammonification), providing a constant supply of ammonia used in the nitrification process. Although atmospheric nitrogen fixation is an important part of the nitrogen cycle, ammonification and nitrification are the preferred methods by which organic nitrogen is prevented from returning to the atmosphere and continues to cycle through the biosphere.

However, some nitrogen is returned to the atmosphere as denitrifying bacteria break down nitrates to produce oxygen, releasing gaseous N in the process

Nitrogen Fixing Plants

. Nitrogen is also lost from plants and soil in terrestrial environments in other ways, including erosion, runoff, ammonia volatilization, and leaching from soil into lakes and streams. Eventually, some of these nutrients end up in the oceans when rivers flush them to the surface of the ocean.

Sulfur is found in all living organisms as a component of some proteins, vitamins and hormones. Like carbon and nitrogen, sulfur cycles between the atmosphere, lithosphere, and hydrosphere; but, unlike these other two elements, it has major reservoirs in both the atmosphere and the lithosphere. As in the nitrogen cycle, the activity of microorganisms is crucial in the global cycle of this nutrient.

The process begins with geochemical and meteorological processes such as weathering of rocks. When sulfur is released from the rock and
