The inside of the cell membrane becomes negative at the time of an action potential.

During an action potential the inside of the cell membrane becomes Blank______ charged.Multiple choice question.negativelypositively

What is produced when depolarization of a cell membrane reaches threshold?Multiple ChoiceA new action potential is produced.The absolute refractory period ends.Voltage-gated ion channels close.An existing action potential is stopped.

During the depolarisation stage of an action potentialThe membrane potential returns to resting conditionsSodium (Na+) enters the cell down it's concentration gradientVoltage gated K+ channels are openPotassium (K+) enters the cell against its concentration gradient

The absolute refractory period assures that action potential propagation isMultiple ChoiceBlocked from certain areas of the cell membraneSpread at a prescribed speedCapable of spreading in either directionOnly in one direction
