Competitive inhibition - Wikipedia

Posted: (2 days ago) Competitive inhibition can be reversible or irreversible. If it is reversible inhibition, then effects of the inhibitor can be overcome by increasing substrate concentration. If it is irreversible, the only way to overcome it is to produce more of the target (and typically degrade and/or excrete the irreversibly inhibited target).

Posted: (12 days ago) A competitive inhibitor typically competes for the active site with the substrate. In this textbook case, binding of a competitive inhibitor is reversible, because it binds to the active site of the enzyme, but is also released, making way for the substrate to bind.

Difference Between Competitive and Noncompetitive Inhibition

Posted: (2 days ago) Summary – Competitive vs Noncompetitive Inhibition. The key difference between competitive inhibition and noncompetitive inhibition is that in competitive inhibition, binding of an inhibitor prevents the binding of the target molecule with the active site of the enzyme whereas, in noncompetitive inhibition, an inhibitor reduces the activity of an enzyme.
