What Effect Would Increasing the Extracellular Concentration of K⁺ have

Multiple Choice

What effect would increasing the extracellular concentration of K⁺ have on the resting membrane potential (RMP) ?

A) Increasing extracellular K⁺ will have no effect on the RMP because it displaces Na⁺.
B) The RMP would become more negative.
C) Increasing extracellular K⁺ will have no effect on the RMP because of the Na⁺/ K⁺ pump.
D) The RMP would become more positive (less negative) .
E) The effects are really seen on the generating potential.
