Question

_________ of excess amino acids in liver produces urea which is excreted by the _________.

• A. Deamination
• B. kidney

Answer 1

Excretion:

1. The process by which the waste products that are harmful to the body are removed from the body is known as excretion.
2. The excretory products are mainly nitrogenous wastes.
3. The nitrogenous wastes are mostly the waste products from metabolic reactions - anabolism and catabolism.
4. In the liver, deamination or breakdown of excess amino acids produces urea.

Filtration:

1. The excretory product urea is transported by the blood to the kidney to be filtered.
2. The process by which the urine is produced by the nephrons is known as uropoiesis.
3. Urine is the excretory fluid that is formed as a filtrate in the filtration process of the kidney.

Deamination of excess amino acids in the liver produces urea which is excreted by the kidney.
