Quizplus · Accepted Answer

An agonist is a substance that enhances or increases the activity of a receptor, while an antagonist is a substance that interferes or inhibits the activity of a receptor. Thus, the relationship between agonist and antagonist can be compared to that of enhance and interfere. Choice A, lock is to key, is not a suitable comparison as the two are not opposing forces. Choice B, block is to mimic, does not accurately reflect the relationship between agonist and antagonist. Choice D, stimulant is to depressant, represents a different type of relationship where the two are opposing forces.
