WebHow Feedback Inhibition Works. Feedback inhibition works by deactivating an enzyme using the product of the reaction the enzyme catalyzes. Enzymes bind to molecules with active sites that are specifically designed to fit with the molecule undergoing the reaction. These enzymes have a second active site for the reaction product to bind to. WebFeedback inhibition occurs when the final product of a pathway controls the rate of its own synthesis through inhibition of its first step. Enzyme inhibition means to stop the enzyme from working.
