What determines the function carried out by a neurotransmitter at a neuron-to-neuron synapse?
A) The type of neurotransmitter released
B) The strength of the action potential generated
C) The type of receptor binding the neurotransmitter
D) The number of neurotransmitter molecules released
E) The rate at which neurotransmitter molecules are released

Question

Quizplus · Accepted Answer

The type of receptor binding the neurotransmitter determines the function carried out by a neurotransmitter at a neuron-to-neuron synapse. Different types of receptors have different effects on the postsynaptic neuron, ranging from excitatory to inhibitory. Therefore, the neurotransmitter will carry out different functions depending on which receptor it binds to.
