Web10 apr. 2024 · The urea is produced from ammonia and carbon dioxide. Protein within the diet is broken down to these constituent amino acids, which are then converted to carbon dioxide, water, and ammonia in the liver. However, ammonia is highly toxic, so it must be removed from the system as soon as possible. WebCorrect option is A) The nitrogen in the amino acid becomes converted to ammonia, and this is further converted by the liver into urea, which is less toxic than ammonia to the body. The kidneys will then filter out the urea from the circulation, send it to the bladder along with water and excrete it in the form of urine. WebHowever, the livercontains a system of carrier molecules and enzymes which quickly converts the ammonia (and carbon dioxide) into urea. This is called the urea cycle. One turn of the cycle: consumes 2molecules of ammonia consumes 1 molecule of carbon dioxide creates 1 molecule of urea((NH2)2CO regenerates a molecule of ornithinefor another turn. mcdowell virginia post office
