it is Carbamoyl phosphate synthase 1 which does the following:
CO2 & NH3 -> Carbamoyl phosphate
don't forget the rate limiting enzyme is stimulated by N-acetylglutamate (NAG)
It's called the Bosch-Meiser urea process. See https://en.wikipedia.org/wiki/Urea
Urease is an enzyme responsible for catalyzing the hydrolysis of urea into carbon dioxide and ammonia. It is produced by various bacteria and fungi and is important in the nitrogen cycle as it helps organisms utilize urea as a nitrogen source.
The urea cycle, which occurs in the liver, converts ammonia to urea. The urea cycle involves a series of reactions that ultimately result in the production of urea, which is then excreted by the kidneys in urine. This process helps to safely remove excess ammonia from the body.
Urea inhibits invertase through non-competitive inhibition by binding to the enzyme at a site other than the active site. This binding results in a conformational change in the enzyme that reduces its activity.
The mechanism of the urea to ammonia reaction involves the breakdown of urea into ammonia and carbon dioxide through the enzyme urease. Urease catalyzes the hydrolysis of urea into ammonia and carbamate, which then decomposes into ammonia and carbon dioxide. This reaction helps in the removal of excess nitrogen from the body through the production of ammonia.
Urea denatures the enzyme as it disrupts the 3-D structure of the enzyme, this changes the shape of the enzymes' active site, thus meaning that the enzyme is unable to create an enzyme-substrate complex which then means that the reaction cannot occur thus the rate of the enzyme controlled reaction becomes very slow.
Agrininosuccinate synthetase is an enzyme that catalyzes the synthesis of argininosuccinate from citrulline and aspartateAs argininosuccinate is in found the urea cycle and the Citrulline-NO cycle the enzyme that produces this is mostly expressed in kidney and liver cells. The gene that codes for the enzyme is found on chromosome 9.

Urease is an enzyme responsible for catalyzing the hydrolysis of urea into carbon dioxide and ammonia. It is produced by various bacteria and fungi and is important in the nitrogen cycle as it helps organisms utilize urea as a nitrogen source.
The enzyme responsible for metabolizing urea is urease. Urease breaks down urea into ammonia and carbon dioxide.
Fumarate and aspartate are the compounds that are linked between the urea cycle and the Krebs cycle. Fumarate from the Krebs cycle can be converted to arginine in the urea cycle, while aspartate from the urea cycle can be converted to oxaloacetate in the Krebs cycle.
The urea cycle takes place in the liver.
The metabolic product of arginine is ornithine and urea. The amino acid arginine is degraded by the enzyme arginase into ornithine and urea. The ornithine can be converted to glutamate that is oxidized to alpha ketoglutarate before it enters the kreb cycle.
The compound regenerated in the urea cycle is ornithine. This compound allows the cycle to continue by combining with carbamoyl phosphate to form citrulline, which is then further processed to produce urea.
ammonium ion, which is the end product of amino acid degradation, is toxic if allowed to accumulate. the urea cycle is a pathway that detoxifies the ammonium ions by converting it to urea - which is then transported to the kidneys to form urine... the function is to remove nitrogen waste from the body and avoid toxicity
Yes, oxaloacetate contributes to the urea cycle by combining with carbamoyl phosphate to form citrulline. This is an important step in the conversion of ammonia into urea for excretion.
The urea cycle, which occurs in the liver, converts ammonia to urea. The urea cycle involves a series of reactions that ultimately result in the production of urea, which is then excreted by the kidneys in urine. This process helps to safely remove excess ammonia from the body.
