For a neuron at rest with a membrane potential of −65 mV, an increase in the movement of potassium ions out of that neuron's cytoplasm would result in the ________.
A) depolarization of the neuron
B) hyperpolarization of the neuron
C) replacement of potassium ions with sodium ions
D) replacement of potassium ions with calcium ions
E) neuron switching on its sodium-potassium pump to restore the initial conditions

Question

Quizplus · Accepted Answer

An increase in the movement of potassium ions out of the neuron's cytoplasm would result in an increase in the negativity of the intracellular environment, causing the membrane potential to become more negative or hyperpolarized.
