Multiple Choice
A cell has a resting membrane potential of -70 mV and ENa = + 60 mV and EK = - 90 mV. If gNa >0 in this cell,
A) The driving force for Na+ is 60 mV, meaning it will enter the cell
B) The driving force for Na+ is 60 m V, m eaning it will exit the cell
C) The driving force forNa+ is -10 m V, m eaning it will enter the cell
D) The driving force for Na+ is + 10 mV, m eaning it will enter the cell
E) The driving force for Na+ is -130 mV, meaning it will enter the cell
