Consider a neuron at rest at 37°C with ion concentrationsinside and outside the cell as at right inside outside

Na+ 10 mM 150 mM
K+ 70 mM 5 mM
i) What is the voltage due to only the difference in concentrations of K+ across the membrane (outside - inside) under these conditions?

ii) What voltage must be applied to the membrane to open a K+channel? In other words, at what voltage are there equalconcentrations of (only) K+ across the membrane?
