Question

what results from the decomposition of neurotransmitter molecules or the reuptake of neurotransmitters from a synaptic cleft?
multiple choice
initiation of synaptic transmission
enhancement of synaptic transmission
end of synaptic transmission

Explanation:

When neurotransmitter molecules are decomposed or re - uptaken from the synaptic cleft, there are no more neurotransmitters available to bind to receptors on the postsynaptic neuron. Synaptic transmission depends on neurotransmitters in the cleft to carry the signal from the presynaptic to the postsynaptic neuron. Without neurotransmitters in the cleft (due to decomposition or reuptake), the signal transmission across the synapse stops.

Answer:

End of synaptic transmission
