Most synapses are thought to employ more than one neurotransmitter, and synapses may be located in close proximity to each other. What receptor property prevents one neurotransmitter (e.g., norepinephrine) from activating a nearby receptor for another neurotransmitter (e.g., acetylcholine)?Multiple ChoiceKeeping different receptor types well separatedRapid reuptake of norepinephrineDifferences in receptor structure A greater diffusion rate for acetylcholine across the synaptic gap

Synaptic knobs :- a- synthesize different types of neurotransmittersb- release neurotransmitters by diffusion across their membranesc- have ligand-gated Ca ++d- are located at the terminal end of dendrites

A postsynaptic neuron responds to neurotransmitters released by a presynaptic neuron by creating

Which statement describes a possible outcome for a neurotransmitter after release into the synaptic cleft?Group of answer choicesActivation of G-protein-coupled receptor on postsynaptic cellModulation by an enzyme, increasing its efficiencyReuptake into postsynaptic terminal via transporter proteinsActivation of voltage-gated ion channel on presynaptic cellUptake into postsynaptic cell via endocytosis

Chemical synapses in the nervous system a- allow diffusion of chemical substances form the presynaptic neuron into the postsynaptic neuronb- allow transmission of potential changes in one direction only; from the presynaptic to the postsynaptic neuronsc- have potential-gated ionic channelsd- are more numerous in the peripheral nervous system than the central nervous system
