It is true that an N-methyl-D-aspartate (NMDA)receptor (Select all that apply.)
A) is activated by glutamate.
B) is a ligand-gated calcium ion channels.
C) opens only when the membrane has been previously depolarized.
D) blockade is associated with enhanced short-term memory.
E) is blocked by a sodium ion.

Question

Quizplus · Accepted Answer

NMDA receptors will not open unless they are bound to glutamine.The NMDA receptor is a ligand-gated calcium ion channel.The N-methyl-D-aspartate (NMDA)receptors are interesting,because they will not open unless the binding of glutamate is paired with a cotransmitter and concurrent depolarization of the membrane.The NMDA receptor is thought to be responsible for long-term memory.The NMDA receptor is blocked by a magnesium ion.
