what do you mean by deamination of excess amino acids in the liver produces urea which is excreted by the kidney ?
Answers
Answer:
The liver controls the amino acid concentration in the body, as excess amino acids which need to be excreted safely. The body is unable to store proteins or amino acids. In the liver ammonia is formed by the deamination of amino acids. ... Excess ammonia is converted to urea.
In the human body, deamination takes place primarily in the liver, however glutamate is also deaminated in the kidneys.
In situations of excess protein intake, deamination is used to break down amino acids for energy.
The amine group is removed from the amino acid and converted to ammonia.
The rest of the amino acid is made up of mostly carbon and hydrogen, and is recycled or oxidized for energy. Ammonia is toxic to the human system, and enzymes convert it to urea or uric acid by addition of carbon dioxide molecules (which is not considered a deamination process) in the urea cycle, which also takes place in the liver.
Urea and uric acid can safely diffuse into the blood and then be excreted in urine.
