AMPA Receptors Influx Mainly Na⁺; NMDA Receptors Influx Both Na⁺

Question

AMPA receptors influx mainly Na⁺; NMDA receptors influx both Na⁺ and Ca²⁺.

Accepted Answer

This statement is true. AMPA receptors allow the influx of mainly Na+ ions and some small amounts of K+ and Ca2+ ions. NMDA receptors allow the influx of both Na+ and Ca2+ ions. The subscripts ^and refer to the different states of the receptor channel, with ^{representing the open state and} representing the closed state.

AMPA receptors influx mainly Na+; NMDA receptors influx both Na+ and Ca2+.
