Answer #1

Answer 1) An agonist drug is a drug that binds to a particular receptor and generates a response by activating it. In contrast, an antagonist works against the agonist drug as it has the opposite function as that of agonist.

Agonists bind to synaptic receptors and enhance the neurotransmitter effect. Examples of working agonist drugs are endorphins like codeine, morphine, and opiate drugs. These drugs bind to neurons resulting in enhancing pleasure and reducing pain.

Note: we could answer the first question unless specified in case of multiple questions.
