multiple choice question
what is amination?

• addition of a nh₂ to a molecule
• addition of a fatty acid to a molecule
• addition of an atp to a molecule
• addition of a phosphate to a molecule

Explanation:

Amination is the process of adding an amino group ($\ce{NH2}$) to a molecule. The other options are incorrect: adding a fatty acid is not amination, adding ATP is not related to amination, and adding a phosphate is phosphorylation, not amination.

Answer:

A. Addition of a $\ce{NH2}$ to a molecule
