Which of the terms best completes the sentence? When amino acids bind a transaminase enzyme, their amino group is transferred to associated with the transaminase before it is transferred to an alpha‑keto acid.

Transamination

Explanation:

Transamination is a chemical reaction that involves the transfer of an amino group from an amino acid to an alpha‑keto acid resulting in the generation of a new alpha‑keto acid and a newly formed amino acid.

For example: Glutamate, an amino acid transfer its amino group to oxalo-acetate, an alpha‑keto acid to generate newly formed amino acid, aspartate and a newly formed alpha-keto acid, α-ketoglutarate.

Thus, transamination is the term that best completes the sentence.
