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

Long-term potentiation is associated with NMDA receptors, which bind to the excitatory neurotransmitter glutamate. When glutamate binds to the NMDA receptor, it opens an internal cation channel within the receptor that allows Ca2+ (calcium ion) influx into the postsynaptic neuron, triggering a cascade of biochemical changes that lead to synaptic strengthening. Therefore, the best choice is B.
