Which statement best describes the biochemical process of transamination in amino acid metabolism?

Transamination removes the carboxyl group from an amino acid and converts it directly into glucose via gluconeogenesis

Transamination refers to the direct incorporation of dietary proteins into muscle without modification

Transamination transfers an amino group from one amino acid (often an essential amino acid) to a carbon skeleton to form a different amino acid, enabling synthesis of nonessential amino acids

Transamination only occurs in the digestive lumen and is unrelated to cellular amino acid interconversion
