Concept:Deamination is the removal of an amino group from an amino acid in the liver, producing the harmless nitrogenous waste called urea.
Explanation:Amino acids that are not needed for protein synthesis are broken down in the liver.
During deamination, the amino group is removed from the amino acid.
This amino group forms ammonia (
NH3), which is highly toxic to body cells.
The liver rapidly converts this toxic ammonia into urea through the urea cycle.
Urea is a much less toxic nitrogenous waste compound.
It is released into the blood, transported to the kidneys, and removed from the body in urine.
Thus, the primary product of deamination in the liver is urea, not blood sugar, glycogen, or bile.
Answer:D. urea
