Question

Which one of the following is the group of herbicide affecting synthesis of amino acids like valine, leucine and isoleucine?

A Sulfonylureas Correct Answer Incorrect Answer
B Triazines Correct Answer Incorrect Answer
C Dinitroaniline Correct Answer Incorrect Answer
D Thiocarbamates Correct Answer Incorrect Answer

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.
