Which Amino Acid is NOT One of the First Amino

Question

Which amino acid is NOT one of the first amino acids produced by ancient cells?
A) glutamate
B) tyrosine
C) glycine
D) valine
E) asparate

Accepted Answer

Tyrosine is not one of the first amino acids produced by ancient cells. The first amino acids produced were likely glycine, alanine, asparate, valine, and glutamate due to their simple chemical structures and ease of synthesis. Tyrosine is a more complex amino acid and is not typically considered to be one of the most ancient.
