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.

WebTwo important functions of the urea cycle are detoxification of ammonia (liver) and provisioning of arginine (kidney) to form urea and ornithine. Two nonprotein amino acids (ornithine and citrulline) are involved in the urea cycle. The C skeleton then can be used for energy, glucose, other amino acids, or ketone body synthesis. WebEach nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney. Two ureters. These narrow tubes carry urine from the kidneys to the bladder.
