When a cell forms an amino acid by adding an amine group derived from ammonia to a precursor metabolite, this process is called
A) amination.
B) transamination.
C) reduction.
D) polymerization.
E) deamination.

Question

Quizplus · Accepted Answer

Amination is the process of adding an amine group derived from ammonia to a molecule, usually a precursor metabolite, to form an amino acid. Transamination, on the other hand, involves transferring an amine group from one amino acid to another molecule to form a different amino acid. Reduction involves adding electrons to a molecule, polymerization involves joining monomers to form a polymer, and deamination involves removing an amine group from an amino acid.
