AP PSYCHOLOGY

Detailed explanation-1: -The excess neurotransmitter in the synaptic gap is either recycled back into the presynaptic neuron or degraded by enzymes in the synapse. When neurotransmitter is released it stimulates receptors on the post-synaptic cell. In order for the signal to stop, the neurotransmitter must be removed from the synapse.

Detailed explanation-2: -Norepinephrine☆ Re-uptake of released NE into presynaptic nerve terminals is responsible for the rapid termination of neurotransmission in noradrenergic synapses. Transport of NE by the neuronal NE transporter (NET) is dependent on extracellular Na+ and Cl−.

Detailed explanation-3: -n. the process by which neurotransmitter molecules that have been released at a synapse are reabsorbed by the presynaptic neuron that released them. Reuptake is performed by transporter proteins in the presynaptic membrane.

Detailed explanation-4: -The synaptic actions of most neurotransmitters are inactivated by reuptake into the nerve terminals from which they are released, or by uptake into adjacent cells.
