Guiding question 4: Now what drives the movement of Na+ (sodium ions) to move into
the cell once the sodium membrane channels open?
Guiding question 1: What is the concentration of the Sodium ions outside of the
membrane (high or low) before start of the action potential during resting membrane
potential?

Respuesta :

electricat and concentration gradients tend to drives sodium ions into the cell while driving potasium out of the cell

the concentration of sodium ions outside of teh membrane is high before the start of an action potential.
