Question

Suppose that an artificial non-gated K^+ channel could be inserted into the plasma membrane of an axon at resting potential (membrane potential = -70 mV). Assume that the axon has not recently produced an action potential. What would happen when an artificial K^+ channel is inserted into an axon membrane at resting potential? Answer questions 1-4 by selecting only from the three answer choices to the left of each question. Drag the correct answer to the right of each question. In what direction will the K^+ ions move through the artificial channel? Does the K^+ concentration gradient promote or impede the movement of K^+ ions through the artificial channel? Does the membrane potential promote or impede the movement of K^+ ions through the artificial channel? How does the movement of K^+ ions through the artificial channel affect the membrane potential?

Explanation / Answer

1.Out of the cell

as the potassium ions move out of the cell.

2.Promote

as K+ concentration gradient promotes the movement of K+ ions.

3.Impede

as the membrane potentioan impedes the movement of K+ ions

4.Causes a hyperpolarization

as this is how the membrane potential gets affects.
