Which of these does not contribute to the cessation of the signal in a synaptic transmission?

A) Synaptic vesicles secrete neurotransmitter by exocytosis.
B) Neurotransmitter escapes from the synapse into the nearby extracellular fluid.
C) Neurotransmitters are no longer released.
D) The axon terminal reabsorbs some neurotransmitters by endocytosis.
E) Enzymes in the postsynaptic cell break down some neurotransmitters.

Synaptic Transmission

The process by which neurotransmitters are released by one neuron and bind to receptors on another, facilitating neural communication.

Neurotransmitter

Chemicals that transmit signals across a synapse from one neuron to another, influencing bodily functions such as mood, appetite, and sleep.

Exocytosis

The process by which cells release substances (such as neurotransmitters or hormones) to the exterior through fusion of vesicles with the plasma membrane.
