- Pick help me pick the appropriate name for the neurons.arrow_forwardAssume a neuron is at rest and the following changes happen: Step 1: Neurotransmitter binds to an ionotropic excitatory neurotransmitter receptor causing an EPSP. Step 2: With the neurotransmitter still bound either a NAM or non-competitive antagonist bind to the allosteric site of the receptor. Answer the following questions that explains how the NAM and non-competitive antagonist would differ in their actions. 4.) A. Going from step 1 to step 2 what would happen to the ionotropic receptor (ion channel) as a result of the NAM. B. Going from step 1 to step 2 what would happen to the ionotropic receptor (ion channel) as a result of the non-competitive antagonist. C. Going from step 1 to step 2 how would membrane potential change as a result of the NAM D. Going from step 1 to step 2 how would the membrane potential change as a result of the non-competitive antagonist.arrow_forwardContrast chemically gated and voltage gated channels.
