Describe the mechanism of enzyme action

Text Solution

Verified by Experts

Each enzyme (E) has a substrate (S) binding site in its molecule substrate binds with it to form enzyme, substrate complex (ES). It dissociates soon into its product(s) P and unchanged enzyme with an intermediate formation of (EP) Enzyme-product complex. The formation of the ES complex is essential for catalysis.
`E + S It can be explained in the following steps :
(1) First, the substrate binds to the active site of the enzyme, fitting into the active site.
(2) The binding of the substrate induces the enzyme to alter its shape, fitting more tightly around the substrate.
(3) The active site of the enzyme, now in the close proximity of the substrate breaks the chemical bonds of the substrate and the new enzyme-product complex is formed.
(4) The enzyme releases the products of the reaction and the free enzyme is ready to bind to another molecule of the substrate and run through the catalytic cycle once again.
