Sulfa drugs bind to the active site of the enzyme which normally converts para-amino benzoic acid (PABA. to folic acid, preventing the production of folic acid and, eventually purine synthesis. In this case, the sulfa drug is acting as a/an:.
a. allosteric inhibitor
b. uncompetitive inhibitor
c. noncompetitive inhibitor
d. competitive inhibitor
