Question

With respect to drug-enzyme interaction, identify the wrong statement.

• A. Competitive inhibitor binds to the enzyme’s active site
• B. Non-competitive inhibitor binds to the allosteric site
• C. Allosteric inhibitor competes with the enzyme’s active site
• D. Allosteric inhibitor changes the enzyme’s active site

Answer 1

The correct option is C Allosteric inhibitor competes with the enzyme’s active site

Some durg do not bind to the enzyme's active site. These bind to a different site of enzyme which called allosteric site. This binding of inhibitor at allosteric site changes the shape of the active site in such a way that substrate can not recognise it. Such inhibitor is known as Non-competitive inhibitor.
Competitive inhibitor binds to the Enzyme's active site.
