Neurotransmitter transporters are a class of membrane transport proteins that span the cellular membranes of neurons.Their primary function is to carry neurotransmitters across these membranes and to direct their further transport to specific intracellular locations.There are more than twenty types of neurotransmitter transporters.or example, some transporters use energy obtained by the cotransport, or symport, of Na+ in order to move glutamate across membranes. Such neurotransporter cotransport systems are highly diverse, as recent development indicates that uptake systems are generally selective and associate with a specific neurotransmitter.

A more subtle form of political corruption is âcronyismâ which involves the appointment of friends to influential positions.
