Question

Quizplus · Accepted Answer

Sulfa drugs, or sulfonamides, work by inhibiting the synthesis of folic acid in bacteria. Folic acid is essential for bacterial growth and replication, and by interfering with its production, sulfa drugs effectively prevent the bacteria from multiplying. This mechanism targets a pathway that is unique to bacteria, making sulfa drugs selective and effective antibiotics.
