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 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

Question

Quizplus · Accepted Answer

An increase in the movement of potassium ions out of the neuron's cytoplasm will result in more negative charge leaving the neuron, causing the membrane potential to become more negative. This is known as hyperpolarization.
