Imagine you have a single neuron growing in culture, bathed in a media that contains the "typical" concentrations of solutes found in human interstitial fluid. You then remove that media and replace it with a different media with a [Na^+] half that of the original media. The otehr conditions of the cell remain the same. What will happen to the cell's resting membrane potential? A. It will decrease (become more negative) slightly, but remain higher than the equilibrium potential of K^+.
B. It will increase (become more positive) slightly, but remain lower than the equilibrium potential of Na^+.
C. It will decrease (become more negative) substantially, settling lower than the equilibrium potential of K^+.
D. It will increase (become more positive) substantially, settling higher than the equilibrium potential of Na^+. E Its membrane potential will not change after the drug treatment.
