The Answer to the question
A. Nitrogen
During anabolic pathways, the process builds large molecules from smaller ones. The correct option is A.
<h3>What is anabolism?</h3>
Anabolism is a group of biosynthetic processes that build larger molecules from smaller ones.
These responses, also known as endergonic processes, require energy. Anabolism is the metabolic process that builds up, whereas catabolism is the metabolic process that breaks down.
Anabolism is the methodology that takes smaller units, such as nutrients, cells, or amino acids, and bonds them together to form larger structures.
Thus, the correct option is A.
