In а few sentences оr less (be cоncise!), explаin the prоcess of neurotrаnsmitter recycling. What happens next to a neurotransmitter that has been secreted and bound to a receptor on the post-synaptic membrane (so, it's already "done its job," then what?)? You do not need to explain the post-synaptic responses here. DO use a specific example of a neurotransmitter in your answer.
