The mechanism of enzymatic action. An enzyme attracts substrates to its active site, catalyzes the chemical reaction by which products are formed, and then allows the products to dissociate (separate from the enzyme surface). The combination formed by an enzyme and its substrates is called the enzyme–substrate complex.

each enzyme has a substrate binding site in its molecule so that a highly reactive enzyme substrate complex is produces this dissociates into its products and unchanged enzyme with an intermediate formation of the enzyme product complex
the catalytic cycle of enzyme action can be described in the following steps
a) first the substrate bind to the active site of enzyme fitting into the active site
b) the binding of the substrate includes the enzyme to alter its shape fitting more tightly around the substrate
c) the active site of enzyme now is close proximity of the substrate breaks the chemical bonds of the substrate and the new enzyme product complex is formed
d)the enzyme releases the products of the reaction and the free enzyme is ready to bind to another molecules of the substrate and run through the catalytic cycle once again

hope it may help u
