WebSep 19, 2024 · Enzyme Inhibition. Enzymes are required for most, if not all, processes required for life. Enzymes catalyse a reaction by reducing the activation energy needed for the reaction to occur. However, enzymes need to be tightly regulated to ensure that levels of the product do not rise to undesired levels. This is accomplished by enzyme inhibition. WebENZYME INHIBITION Prepared by D.Anderson-Rowe fENZYME INHIBITION A variety of small molecules exists that can reduce the rate of an enzyme- catalysed reaction. They are called enzyme inhibitors. Inhibition is a normal part of the regulation of enzyme activity within cells. Many drugs and poisons also act as enzyme inhibitors.
