Question

Separately, draw a table using arrows to depict the appropriate magnitude and direction of the forces and ion fluxes at different membrane potentials for a ligand-gated channel that is equally permeable to both ion X? and ion Y?. The equilibrium potential for ion X? is -60 mV, and the equilibrium potential for ion Y? is -20 mV. Which item best represents the forces and fluxes for a membrane potential of +40 mV?
