Question

The organ which produces urea is .

Answer 1

Hint: Urea is a nitrogen-containing compound with simple molecular structure \[N{{H}_{2}}CON{{H}_{2}}\]. The nitrogen in urea comes from amino acids, and it is a component of urine.

Complete Answer:
- The nitrogenous waste in the human body is ammonia. that is a toxic compound for the human body. This ammonia has to be converted into a non-toxic substance that is, urea with the help of some enzymes that are found only in the liver.
- Five enzymes that are involved in the synthesis of urea are; Carbamoylphosphate synthase (CPS), ornithine Carbamoyltransferase (OCT), Argininosuccinate synthase, Argininosuccinate lyase, and arginase.Urea is an excretable form.

So, the Liver is the correct answer.

Additional information: The conversion of ammonia into urea is a two-step process, where the ammonia and carbon dioxide react to each other and form ammonium carbamate which is then dehydrated to urea. This process is called the urea cycle.
- To produce a molecule of urea two molecules of ammonia and one molecule of carbon dioxide are required.
- The ammonia comes from the metabolism of nitrogen-containing molecules such as amino acids, and carbon dioxide is a by-product of the Krebs cycle.
- Typically, \[25-30\text{ }g\] of urea is excreted out per day.
 - The concentration of the urea tells about how much protein has been taken with diet, one’s ability to catabolize, or breakdown the protein. if there is an abnormal level of the urea in the blood, it indicated that kidneys are not working normally.

Note: The production and excretion are two different things. Urea is produced by the liver and excreted by the kidneys.
