The primary nitrogenous end product of metabolism in humans is urea, which is a waste product of amino acid metabolism.

Here's a step-by-step explanation:

1. When proteins are consumed in the diet, they are broken down into their constituent amino acids by enzymes in the stomach and small intestine.

2. These amino acids are then absorbed into the bloodstream and transported to the liver.

3. In the liver, the amino acids undergo deamination, a process that removes the amino group (NH2). This process produces ammonia (NH3), which is toxic to the body.

4. The liver cells quickly convert this ammonia into urea, a much less toxic compound, through a process called the urea cycle.

5. The urea is then released into the bloodstream, where it is transported to the kidneys and excreted in the urine.

So, urea is the primary nitrogenous end product of metabolism in humans, and it is a waste product of amino acid metabolism.
