bond covalently to the active site of the enzyme.
48. How do competitive and noncompetitive enzyme inhibitors differ?
Competitive inhibitors bind to the active site, whereas noncompetitive inhibitors change the shape of the active site.
Competitive inhibitors have a higher energy of activation than noncompetitive inhibitors have.
They function at different pH values.
Noncompetitive enzyme inhibitors contain magnesium, whereas competitive inhibitors contain iron.
Noncompetitive enzyme inhibitors are reversible, whereas competitive inhibitors are irreversible.
