Long-term potentiation is associated with NMDA receptors,one of several types of receptors that bind to the excitatory neurotransmitter _______.Its binding opens an internal cation channel within the receptor that allows _____ influx into the postsynaptic neuron,triggering a cascade of biochemical changes that lead to synaptic strengthening.
A)GABA,Ca2+ ion
B)glutamate,Ca2+ ion
C)glutamate,K+ ion
D)GABA,K+ ion
E)acetylcholine,Ca2+ ion

Question

Quizplus · Accepted Answer

Glutamate is the excitatory neurotransmitter associated with NMDA receptors. When glutamate binds to NMDA receptors, it opens an internal cation channel that allows Ca2+ ion influx into the postsynaptic neuron, leading to long-term potentiation.
