You Isolate the Enzyme That Synthesizes Folic Acid in Bacteria

question 62

Multiple Choice

You isolate the enzyme that synthesizes folic acid in bacteria and conduct some enzyme kinetics experiments. You find, not surprisingly, that sulfa drugs inhibit the enzyme's activity. What happens to the V_max and K_M of this enzyme when it is treated with sulfa drugs? (Select all the correct statements relating to this experiment)

• A)sulfa drugs are competitive inhibitors of the folic acid synthesis pathway
• B)V_max will stay the same and K_M of this enzyme will decrease
• C)V_max will decrease and K_M of this enzyme will stay the same
• D)V_max will increase and K_M of this enzyme will increase
• E)V_max will stay the same and K_M of this enzyme will increase
