Q5.5. Why do neurons generate an action potential, instead of simply relying on the opening of ion channels near the stimulus site to transmit information? Because, without the action potential, changes in Vm at the stimulus site might not reach the axon terminal Because without the action potential, the neuron would not depolarize Because action potentials help the body keep ion concentrations at appropriate levels Because, without the action potential, the neuron would not return to resting potential Submit
