Question

Action potentials

are initiated by the membrane's increased permeability to potassium.

B)return to resting when the sodium channels open.

C)can be triggered in very rapid succession, with no delay.

involve voltage-gated channels in the membrane.

are propagated only when chloride ions move through the membrane.

are propagated only when chloride ions move through the membrane.

D. involve voltage-gated channels in the membrane.

Action potentials are generated by special types of voltage-gated ion channels embedded in a cell's plasma membrane.
