Sulfa drugs like Bactrim, given for bacterial infections, inhibit bacteria by blocking folic acid synthesis. The precursor molecule of folic acid is para- amino benzoic acid (PABA). Interestingly, PABA has a structure very similar to a sulfa drug. If a sulfa drug is present, the bacterial enzyme will bind the sulfa drug because of structural similarity. This is an example of Select one: a. enzyme induction b. enzyme repression c. noncompetitive inhibition d. competitive inhibition e. catabolite repression
