Explain Allosteric site.

Answer»

Solution :(ii) Some drugs to not bind to the enzyme’s active site. These bind to a different site of enzyme which is called allosteric site.
This BINDING of inhibitor at allosteric site CHANGES the shape of the active site in such a way that substrate cannot recognise it.

If the bond formed between an enzyme and cannot be broken easily, then the enzyme is BLOCKED permanently. The BODY then degrades the enzyme - inhibitor complex and synthesises the NEW enzyme.
