Question
Which one of the following is the group of herbicide
affecting synthesis of amino acids like valine, leucine and isoleucine?Solution
Sulfonylurea herbicides inhibit the enzyme acetolactate synthase (ALS), which is involved in the biosynthesis of branched-chain amino acids such as valine, leucine, and isoleucine. By inhibiting this enzyme, sulfonylurea herbicides disrupt the production of these essential amino acids, leading to the death of susceptible plants.
