Quizplus · Accepted Answer

This is noncompetitive inhibition because the molecule is not competing with the substrate for the active site, but rather altering the shape of the active site itself. Competitive inhibition occurs when a molecule competes with the substrate for the active site. Irreversible inhibition involves a molecule binding covalently to the enzyme and permanently altering its activity. Activation and covalent modification involve processes that enhance enzyme activity rather than inhibit it.
