Which of the Following Molecules Uses Chorismate as a Precursor

Question

Which of the following molecules uses chorismate as a precursor?
A)p-aminobenzoic acid
B)coenzyme Q
C)phenylalanine
D)tryptophan
E)all of the above

Accepted Answer

All of the given molecules use chorismate as a precursor. P-aminobenzoic acid is derived from the shikimate pathway and requires chorismate as a precursor. Coenzyme Q also requires chorismate for its biosynthesis, and it is synthesized through the isoprenoid pathway. Phenylalanine and tryptophan are aromatic amino acids that are synthesized through the shikimate pathway and also require chorismate as a precursor molecule.
