The uneven distribution of ions across the plasma membrane is regulated, in part, by transport proteins. The result is a net negative charge on the inside of the plasma membrane and a net positive charge on the outside of the plasma membrane. How do you explain the net negative charge inside the plasma membrane when the predominant intracellular ion is K+?

Ion channels in developing membrane potentials There are two kinds of ion channels: (gated / leakage) channels that randomly open and gated channels that require a stimulus to activate opening of closure. The plasma cell of a membrane is more permeable to (K+ / Na+) because there are more leakage channels for (K+ / Na+). If K+ did freely leak out of the membrane that is so permeable to it, the inside of the membrane would become increasingly (negative / positive), contributing to a (negative / positive ) membrane potential.

Ions are unequally distributed across the plasma membrane of all cells. This ion distribution creates an electrical potential difference across the membrane. What is the name given to this potential difference?

The plasma membrane represents an energetic barrier to the free diffusion of ions from the extracellular space into the cytoplasm. Why are molecules such as valinomycin effective at transporting ions across the membrane? Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?
