In neurotransmission at the synapse, after a neurotransmitter is released, it diffuses across the synaptic cleft and ___________.
A)attaches to receptor sites on the receiving cell
B)continues travelling down the axon of the next neuron as an action potential
C)never actually touches the receiving neuron but acts as a stepping stone for the action potential to skip across the gap and keep travelling down the next neuron
D)uses ion channels to enter the next neuron

Question

Quizplus · Accepted Answer

Neurotransmitters diffuse across the synaptic cleft and bind to specific receptor sites on the post-synaptic neuron, initiating a response in the receiving cell. This is a fundamental process in neurotransmission.
