The effector molecule binding at a regulatory site causing an alteration of the enzyme's active site geometry and loss of activity is an example of noncompetitive inhibition. This type of inhibition is freely reversible, meaning that the effector can be released from the regulatory site, allowing the enzyme to regain its activity. Competitive inhibition involves the binding of a molecule at the active site, preventing substrate binding, while passive enzymatic regulation and covalent modification involve other mechanisms of regulation. Irreversible inhibition involves the irreversible modification of an enzyme, leading to permanent loss of activity.
