In the body, excess amino acids are a. burned as fuel or stored as fat b. of no concern to health status c. directly converted into lean muscle mass d. stored by the body in the form that they were consumed

a. burned as fuel or stored as fat

Explanation:

Excess amino acid are removed by the liver in a process known as deamination.

During this process, the amine group in the excess amino acid are removed and converted into ammonia which eventually gets converted into urea or uric acid by an enzyme.

The remaining portion of the amino acid is converted into carbohydrate or fat and oxidized when necessary to generate energy for the body.

Hence, the correct option is a.

a. burned as fuel or stored as fat b.

Explanation:

Excess Amino Acids as a result of high protein diet is first deaminated primarily in the liver, and also in the kidney, to make it non toxic.

it is the process of first removing the amine group NH2, by converting it to poisonous ammonia by the liver, This is quickly converted by the liver to non-poisonous Urea, and transported to the kidney for excretion.

The removal of amine group is done by enzyme Glutamate Dehydrogenase (GDH) in the mitochondria, in the process of Glutamate deamianation. This enzyme cleave / remove the Amine group of the Amino acids to form Ammonia and ∝-ketoglutarate in the liver.

The Ammonia is converted to Urea, by the liver, and transported to the kidney, while the ∝-Ketoglutarate made of carbons skeletons and hydrogen, (now free of Nitrogen group) enters the kreb's Cycle pathways of ATP s synthesis. This ends the process of deamination.

In case of excess amino acids beyond what the body can cope with this is converted to fats, and stored in adipose tissues.
