Answers
Answer:
It is formed by the separation of waste materials by kidneys
Answer:
The liver carries out over 200 different roles in the body. All the blood from digestive system flows to liver FIRST before going into the rest of the circulation. The amino acids produced in the alimentry canal by the digestion of protein are absorbed into the blood in the small intestine. Because our body cannot store amino acids,they are broken down into two parts. One of them is made into UREA.
Amino acids cannot be stored so the liver breaks down amino acids that are not required for making proteins. Each amino acid molecule is broken down into two by the process called deamination. One molecule is converted to carbohydrate or fat and used as a source of energy. The other molecule is ammonia(NH3) which combines with carbon dioxide to form excretory product UREA.Afterwards,this is carried to the kidneys in the blood where it is filtered out and is excreted in urine.
The part of the amino acid molecule that contains nitrogen is known as the amine group.This is why the process is called deAMINation.
