Enzymes are proteins which accelerate the chemical reaction in the cell. A special portion of the enzyme which is called "active side" is formed in such a way as to fit with the specific substrate molecules.
The enzyme works by binding to one or more specific molecules called "substrate".
Connection occurs on the active side. The enzyme and substrate form a complex enzyme substraten.
The interaction between the enzyme and the substrate either increases or decreases any of the chemical bonds in the substrate.
As a result of the chemical interactions in the active part, to form a new product.
He then released from the active start of the enzyme acquires its normal shape and is ready to work again.
