The increased influx of calcium at a postsynaptic terminal with glutamate receptors
A) activates the AMPA receptor to increase sodium influx.
B) activates a protein kinase that phosphorylates the NMDA receptor, making it more sensitive to glutamate.
C) activates a protein kinase that phosphorylates the AMPA receptor, making it more sensitive to glutamate.
D) activates the NMDA receptor to increase calcium influx.
E) causes a greater release of neurotransmitter from the postsynaptic cell.

Question

Quizplus · Accepted Answer

Calcium influx at the postsynaptic terminal can activate protein kinases that phosphorylate AMPA receptors, increasing their sensitivity to glutamate and enhancing synaptic transmission.
