Which of the following describes the primary mechanism of action of sulfonamides?
Show answer and explanation
Correct answer: Competitive inhibition of dihydropteroate synthase
Sulfonamides are structural analogs of p-aminobenzoic acid (PABA). They competitively inhibit dihydropteroate synthase, the enzyme responsible for incorporating PABA into dihydropteroic acid, a precursor of folic acid.
