Explain the mechanism of enzyme catalysis.

Explanation

Step 1 : There are a number of active centres on the surface of the enzyme. The molecules of the reactant (substrate) which have complementory shape to the enzyme fit into active centres like a key fits into a lock and foms an activated complex.
`E + S rarr RS^(**)`
Step II : Decomposition of activated complex gives the products.
`ES^(**) rarr E + P`
