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.

Action potentials travel fastest on large diameter, myelinated axons.Group startsTrue or FalseTrue, unselectedFalse, unselected

A recently depolarized area of a cell membrane cannot generate an action potential because of theMultiple Choiceabsolute refractory period.high concentration of sodium ions in the extracellular fluid.the high concentration of potassium ions in the cytoplasm.presence of receptor sites on the membrane.
