Urea is a product of the metabolism, not anabolism – building – of amino acids, which is why answer B is incorrect.

“Unlike fat or carbohydrate, the human body has limited capacity to transiently store ‘excess’ dietary protein from a single meal to acutely stimulate muscle protein anabolism at a later time.”

Pertaining to anabolism; an anabolic changes, or processes, more or less constructive in their nature.

We may thus regard every centre of anabolism as a negative pole of diffusion.

The processes concerned in metabolism are chiefly those of building up, “anabolism,” and breaking down, “catabolism.”
