Nitrogen metabolism refers to the biochemical processes through which organisms convert nitrogen from various sources into usable forms, primarily for the synthesis of amino acids, nucleotides, and other nitrogen-containing compounds. This process includes nitrogen fixation, where atmospheric nitrogen (N₂) is converted into ammonia (NH₃) by certain bacteria, as well as the assimilation and dissimilation of nitrogen in plants and animals. In humans and other animals, nitrogen metabolism is crucial for the breakdown of amino acids and the excretion of nitrogenous waste, primarily in the form of urea. Overall, nitrogen metabolism is essential for maintaining cellular function and supporting growth and development.
What else can I help you with?
What are needed for cellular metabolism between oxygen and nitrogen?
oxygen
What does a chlamydomonas make from nitrogen?
Chlamydomonas, a type of algae, can incorporate nitrogen into proteins, chlorophyll, and other essential molecules required for growth and metabolism. Nitrogen is an essential nutrient for the synthesis of these biological molecules in chlamydomonas.
What is the end product of nitrogen metabolism?
The end product of nitrogen metabolism is urea, which is produced in the liver from the breakdown of amino acids. Urea is then excreted by the kidneys in urine as a way for the body to eliminate excess nitrogen.
Urea results from the metabolism of?
Urea results from the metabolism of protein in the liver. Amino acids are broken down during protein metabolism, and the waste product urea is formed as a way to eliminate excess nitrogen from the body.
What do ammonia urea and enzymes have in common?
Ammonia, urea, and enzymes are all involved in biological processes. Ammonia and urea are nitrogenous waste products produced during the breakdown of proteins, while enzymes are proteins that catalyze chemical reactions in living organisms. Enzymes can be involved in the metabolism of ammonia and urea to regulate nitrogen metabolism in the body.
What is the principal nitrogen excretion product of metabolism?
The principal nitrogen excretion product of metabolism in humans is urea. It is produced in the liver as a way to remove excess nitrogen from the body, which is generated during protein metabolism. Urea is then excreted by the kidneys in the urine.

Can working out produce urea - waste Nitrogen from the metabolism of proteins - in urine?
Yes, quite commonly.
Why does the liver produce urea?
Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals.
What is the function of a heterocyst in cyanobacteria?
A heterocyst in cyanobacteria is a specialized cell that helps in nitrogen fixation, converting atmospheric nitrogen into a form that can be used by the organism for growth and metabolism.
What does a chlamydomonas make from nitrogen?
Chlamydomonas, a type of algae, can incorporate nitrogen into proteins, chlorophyll, and other essential molecules required for growth and metabolism. Nitrogen is an essential nutrient for the synthesis of these biological molecules in chlamydomonas.
What is the key enzyme in nitrogen fixation?
The key enzyme in nitrogen fixation is nitrogenase. This enzyme is responsible for converting atmospheric nitrogen (N2) into ammonia (NH3), which can be used by plants and other organisms for growth and metabolism.
