Question

Quizplus · Accepted Answer

An agonist is a drug that increases the action of a neurotransmitter by binding to and activating the receptor sites on the postsynaptic neuron. Mimickers are substances that resemble a neurotransmitter, but may not necessarily increase its action. Protagonists are main characters in a story, and not related to neurotransmitters or drugs. Antagonists are drugs that bind to and block the receptor sites, reducing the action of a neurotransmitter.
