WebJul 4, 2024 · One method of regulating enzymes is via reversible and irreversible inhibition. In these processes, a small molecule or ion called the inhibitor binds to the enzyme and inhibits its activity. There are three major types of reversible inhibition processes - competitive inhibition, noncompetitive inhibition and uncompetitive inhibition.
