If EK = -85 mV and E m = -70 mV , the potassium current is A) Positive, meaning that I_K is outward and K⁺ B) Po sitive, mean ing that I_K is inward and K⁺ flow is inward C) Ne gative , meaning that I_K is outward and K⁺ Flow is outward D) Negative , meaning that I_K is inward and K⁺ flow is inward E) Cannot tell without knowing g_K

Question

Quizplus · Accepted Answer

When the membrane potential (Em) is more positive than the equilibrium potential for potassium (EK), the potassium current is positive, indicating an outward flow of K+ ions.
