Question

Quizplus · Accepted Answer

A molecule that mimics the effects of a neurotransmitter and binds to its receptor site is called an agonist. Glutamate is a neurotransmitter, but not all agonists act on glutamate receptors. Steroids are a type of molecule that can act as hormones or signaling molecules, but they are not necessarily agonists. Action potential refers to the brief electrical charge that travels down a neuron's axon, and is not a drug molecule nor does it bind to neurotransmitter receptors.
