Question

Which of the following is true regarding an IPSP?

a) it will occur if a ligan-gated sodium channel is opened

b) it can be generated by epinephrine

c) If it’s large enough, one of them it can lead to an action potential being generated

d) the neuron’s membrane potential will become more megative

e) if it’s a large enough potassium voltage gated channels will open

Answer 1

b) it can be generated by epinephrine d) the neuron’s membrane potential will become more negative

Inhibitory post synaptic potential considered as the hyperpolarization of the postsynaptic membrane which arise due to the flow of negatively charged ions into postsynaptic membrane of the cell.Therefore, it occurs if a ligand gated sodium channel is closed.The potassium voltage channel will remain closed.The action potential can't be generated until the rapid opening in voltage gated sodium channels that proceeds to influx of the sodium ion into the cells.The binding of neurotransmitters (epinephrin) binds to its receptor causes the opening of ion channels in post syanaptic membrane in IPSP.
