26. When it comes to ligand-gated ion channels located in a postsynaptic neuron's membrane, why are they so important with respect to how synapses pass along information?

		These channels allow specific neurotransmitters originating in the presynaptic neuron exert effects on the postsynaptic neuron.
		These channels are located specifically in the dendrites but not another part of the neuron, such as the axon.
		These channels open when a given amount of electrical signal in generated in the cell's membrane.
		These channels allow the neurotransmitter to enter and travel within the postsynaptic neuron.

25. When the receptor of a sensory neuron is activated and a nerve impulse is generated, the first step in the overall process would be ____________________________.
