Question
Which of the following statements is not true about enzyme inhibitors?
Options
Inhibit the catalytic activity of the enzyme.
Prevent the binding of substrate.
Generally a strong covalent bond is formed between an inhibitor and an enzyme.
Inhibitors can be competitive or non-competitive.
Solution
Generally a strong covalent bond is formed between an inhibitor and an enzyme.
Explanation:
Inhibitors are chemical substances that tend to reduce the activity of a particular enzyme. Generally, a weak bond such as H-bonding, van der Waals interaction, etc. is formed between the enzyme and the inhibitor.

What happens when the bond formed between an enzyme and an inhibitor is a strong covalent bond?
Assertion: Enzymes have active sites that hold substrate molecule for a chemical reaction.
Reason: Drugs compete with natural substrate by attaching covalently to the active site of enzyme.
Assertion: Competitive inhibitors compete with natural substrate for their attachment on the active sites of enzymes.
Reason: In competitive inhibition, inhibitor binds to the allosteric site of the enzyme.
Assertion: Non-competitive inhibitor inhibits the catalyic activity of enzyme by binding with its active site.
Reason: Non-competitive inhibitor changes the shape of the active site in such a way that substrate can’t recognise it.
