Which statement is true about potassium during resting membrane potential?
A) Potassium is on the outside of the neuron cell membrane.
B) Potassium can freely cross the neuron cell membrane.
C) Potassium is attracted to positive ions on the inside of the cell.
D) Potassium must have an open channel to cross the neuron membrane using active transport.

Question
