If EK = -85 MV and E M = -70

Question

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

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.
