Question

The aromatic amino acids are synthesized in humans by a pathway beginning with reaction of indole with serine. synthesized in bacteria in a pathway shared by all three, up to the production of the intermediate chorismate. synthesized by first making phenylalanine and then deriving tyrosine and tryptophan from phenylalanine. derived from acetyl Co‑A.

Answer 1

The aromatic amino acids are

Synthesized in bacteria in a pathway shared by all three, up to the production of the intermediate chorismate.

Chorismate, the metabolite of the shikimate pathway serves as the initiator substrate for the synthesis of the three aromatic amino acids in bacteria.
