Step-by-step explanation
Antagonists are substances that interfere with or inhibit the physiological action of another. They bind to receptors but do not activate them, and instead block the receptors from being activated by other substances.
Statement A is true. Antagonists do bind to the receptor site, blocking it from being activated by other substances.
Statement B is not typically true. Antagonists work by binding to the receptor site on the cell surface, not by being transferred inside the cell.
Statement C is true. By blocking the receptor site, antagonists can inhibit the natural communication of the body.
Statement D is not true. Antagonists do not mimic the natural messenger. They block its action instead. This is in contrast to agonists, which do mimic the action of the natural messenger.
Therefore, Option C "A and C" is the correct answer.
