WebIrreversible Inhibitors form strong covalent bonds with an enzyme. These inhibitors may act at, near, or remote from the active site. Consequently, they may not be displaced by the addition of excess substrate. In any … WebReversible inhibitors are those inhibitors which bind to the enzyme in a reversible fashion. They do not form a dead complex. The enzyme-substrate complex dissociates rapidly. There are three types of reversible inhibitors which are described in the below image.
