If the potassium ion concentration is 3 mM outside and 88 mM in the cytoplasm, and potassium selective channels open with the membrane potential at -30 mV, which will occur?
A) The net flux of potassium ions will be inward.
B) The net flux of potassium ions will be outward.
C) There will be no net flux of potassium ions-it will be equal in and out.
D) There will be no movement of potassium ions across the membrane.
E) Potassium channels will inactivate
