Question

For a neuron with an initial membrane potential at -70mV , 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

Answer 1

For a neuron with an initial membrane potential at -70mV, an increase in the movement of potassium ions out of that neuron's cytoplasm would result in B. Hyperpolarization of the neuron.

A normal neuron's resting potential (potential across the membrane) ranges from -60 millivolts to -70 millivolts. This indicates that the cell's interior is negatively charged in comparison to the exterior.

When the membrane potential shifts more negatively at a specific location on the neuron's membrane, this is known as hyperpolarization. Hyperpolarization may result from the opening of channels that allow positive ions to exit the cell or negative ions to enter.

Example:  Hyperpolarization may result from the opening of channels that allow potassium ions to exit the cell.
