During a normal synaptic transmission, after the neurotransmitters are released from the post synaptic membrane, what happens to the neurotransmitters?
A) They move into the post synaptic neuron.
B They are broken down by enzymes.

C
They return to the pre-synaptic neuron.

D
Both b and c.

Respuesta :

Both b and c.

In order to remove the neurotransmitters from the synaptic cleft, there are transporter proteins on the pre-synaptic neuron which transport neurotransmitters back into the neuron where they are repackaged into vesicles in preparation for repeated release later. There are also enzymes present in the synaptic cleft which degrade the neurotransmitters.

Extra info: There is a third way in which neurotransmitters leave the synaptic cleft, and this is that they simply diffuse away.
