Which of the following statements is correct?
पर्याय
Some tranquilisers function by inhibiting the enzymes which catalyse the degradation of noradrenaline.
Tranquilisers are narcotic drugs.
Transquilisers are chemical compounds that do not affect the message transfer from nerve to receptor.
Tranquilisers are chemical compounds that can relieve pain and fever.
उत्तर
Some tranquilisers function by inhibiting the enzymes which catalyse the degradation of noradrenaline.
Explanation:
Tranquilizers are neurologically active drugs. Some tranquilizers are antidepressants and the functions by inhibiting the enzymes which catalyse the degradation of noradrenaline.
If the enzyme is inhibited, the neurotransmitter noradrenaline is slowly metabolized and can thus activate the receptor for longer periods there by counteracting the effect of depression. Tranquilizers form an essential component of sleeping pills.

Explain the role of allosteric site in enzyme inhibition?
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: 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.
How do enzymes catalyse a chemical reaction in the living system? Explain drug target interaction taking the example of enzyme as target.
