EXCRETION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When proteins are deaminated, toxic ____ forms and must be excreted.
A
urea
B
uric acid
C
ammonia
D
amino acids
Explanation: 

Detailed explanation-1: -Typically in humans, deamination occurs when an excess in protein is consumed, resulting in the removal of an amine group, which is then converted into ammonia and expelled via urination. This deamination process allows the body to convert excess amino acids into usable by-products.

Detailed explanation-2: -In situations of excess protein intake, deamination is used to break down amino acids for energy. The amino 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.

Detailed explanation-3: -Most of our nitrogenous waste comes from the breakdown of amino acids. This occurs by deamination. Deamination of amino acids results in the production of ammonia (NH3).

Detailed explanation-4: -The liver is a complex organ. It performs over 500 different functions. Two of these are the control of amino acid concentration and detoxification.
