question 12

Multiple Choice

A cell has a resting membrane potential of -70 mV and E_Na = + 60 mV and E_K = - 90 mV. If g_Na >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
