Enzymes are biological catalysts that catalyze chemical reactions or biochemical reactions. They are substrate specific and each enzyme acts on a certain specific substrate.
<em><u>Enzymes contain a pocket-like structure called the </u></em><em><u>active site</u></em><em><u> where the substrate binds according to the induced-fit model.</u></em>
Upon binding of the substrate to the active site catalysis takes place and the substrate is converted to product. Enzymes remain unchanged after the reaction.
