Question

Chorismate is a precursor in the synthesis of all of the following except _______.
A) Phenylalanine
B) Tryptophan
C) Ubiquinone
D) Tyrosine
E) Guanidoacetate

Accepted Answer

Chorismate is a precursor for the synthesis of the aromatic amino acids phenylalanine, tryptophan, and tyrosine, as well as other aromatic compounds like ubiquinone. Guanidoacetate, however, is not synthesized from chorismate; it is a precursor to creatine, synthesized from arginine and glycine.
