1. Non-competitive inhibition of an enzyme can be overcome by adding large amount of substrate
2. Competitive inhibition is seen when a substrate competes with an enzyme for binding to an inhibitor protein
3. Competitive inhibition is seen when the substrate and the inhibitor compete
4. Non-competitive inhibitors often bind to the enzyme irreversibly
Competitive inhibition is seen when the substrate and the inhibitor compete
