The nitrogenous waste in the blood is the result of protein catabolism.

Here's the step by step explanation:

1. Proteins are large molecules made up of amino acids.

2. When the body needs to break down proteins for energy, it carries out a process called protein catabolism.

3. During protein catabolism, proteins are broken down into their constituent amino acids.

4. The amino acids are then deaminated, a process in which the amino group (-NH2) is removed.

5. The removal of the amino group produces ammonia (NH3), which is toxic to the body.

6. The liver converts this ammonia into a less toxic substance called urea, which is a nitrogenous waste product.

7. This urea is then transported by the blood to the kidneys, where it is excreted in the urine.

So, the nitrogenous waste in the blood is a direct result of protein catabolism.
