Mr. Reynolds had an increase in his blood urea nitrogen (BUN). BUN is a measure of the amount of nitrogen in the blood that comes from urea, which is normally eliminated by the kidneys. Determine the specific type of metabolism that causes urea to be
present in the blood.
What will be an ideal response?
Urea is a product of amino acid metabolism. Amino acid catabolism begins in the liver with deamination by the process of transamination, which yields a carbon skeleton and the amino acid glutamate. The carbon skeleton is converted into a variety of compounds that are fed into glycolysis or the citric acid cycle. Glutamate is deaminated and the ammonia enters the urea cycle to produce urea, which is eliminated from the body by the kidneys.
