Solution

An antagonist is a substance that:

a. Binds to the receptors without directly altering their functions

An antagonist is a type of substance that interacts with receptors in the body, but unlike other substances, it does not directly alter the function of these receptors. Instead, it blocks or dampens the biological response that would normally be triggered by other substances, such as hormones or neurotransmitters. This can help to regulate overactive bodily responses or to prevent certain types of cellular damage.

For example, certain types of drugs used to treat conditions like hypertension or allergies work as antagonists. They bind to specific receptors in the body and block the action of substances that would normally cause an increase in blood pressure or an allergic reaction.
