For a neuron with an initial membrane potential at -70 mV, an increase in the movement of potassium ions out of that neuron’s cytoplasm would result in A) the depolarization of the neuron. B) the hyperpolarization of the neuron. C) the replacement of potassium ions with sodium ions. D) the replacement of potassium ions with calcium ions. E) the neuron switching on its sodium-potassium pump to restore the initial conditions.
