What is the process called when urea is formed?
It's called the Bosch-Meiser urea process. See https://en.wikipedia.org/wiki/Urea
What is the function of urease?
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.
What converts ammonia to urea?
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.
What is the type of inhibition of invertase by urea?
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.
What is the mechanism of the urea to ammonia reaction?
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.
How does the addition of urea affect the rate of enzyme reaction?
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.
Where in a cell is argininosuccinate synthetase found?
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.

What enzyme is responsible for metabolizing urea?
The enzyme responsible for metabolizing urea is urease. Urease breaks down urea into ammonia and carbon dioxide.
Which compounds involved in the urea cycle are linked to the Krebs cycle?
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.
Where does the urea cycle take place in the body?
The urea cycle takes place in the liver.
Which is the metabolic product of arginine?
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.
What compound is regenerated in the urea 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.
Where does urea cycle takes place?
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
Does oxaloacetate contribute to the urea cycle?
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.
