A noncompetitive antagonist will do all of the following except:
A) prevent a neurotransmitter from activating a receptor.
B) prevent a neurotransmitter from binding to receptor.
C) bind to a site different from the neurotransmitter binding site.
D) fail to cause a conformation change in the receptor.

Question

Quizplus · Accepted Answer

Noncompetitive antagonists typically bind to a site different from the neurotransmitter binding site (allosteric site) and can prevent the neurotransmitter from activating the receptor without preventing the neurotransmitter from binding to its receptor. They may cause a conformational change in the receptor that reduces its activity, but they do not directly block the neurotransmitter binding site.
