Select the correct statement
Options
- AAntagonists are the substances which inhibit the natural function of receptor site
- BAgonists are the drugs that mimic the natural messenger by switching on the receptor
- CSubstrates may bind to active site of enzyme through the variety of interactions such as ionic bonding, H-bond
- DAll of these
Correct answer
D. All of these
Step-by-step solution
There are a large number of different receptors in the body that interact with different chemical messengers. These receptors show selectivity for one chemical messenger over the other because their binding sites have different shape, structure and amino acid composition. Drugs that bind to the receptor site and inhibit its natural function are called antagonists. These are useful when blocking of message is required. There are other types of drugs that mimic the natural messenger by switching on the receptor, thes
