The NMDA receptor
A) selectively opens channels for sodium, but not calcium.
B) is blocked by the antagonist NBQX.
C) has only a single binding site.
D) is responsive to both glutamate and glycine.

Question

Quizplus · Accepted Answer

The NMDA receptor is responsive to both glutamate and glycine. It is a ligand-gated ion channel that permits the flow of both sodium and calcium ions into the cell. Additionally, it contains multiple binding sites, including those for glutamate, glycine, and the antagonist NBQX. Therefore, choices A and B are incorrect, and choice C is also incorrect as the receptor has multiple binding sites.
