Summary Introduction
To review:
Blocking of an enzyme by drugs and poisons can lead to cell death.
Introduction:
Enzymes are the biocatalysts. They are made up of proteins, the polypeptide chains of which are arranged in a definite three-dimensional structure, to catalyze a biochemical reaction. The enzyme has multiple sites to bind with the substrate. When a substance other than the substrate binds to the enzyme at the substrate binding site or at any other site, the activity of the enzyme gets inhibited. Such substances are known as inhibitors.
