The membrane potential in a cell derives ultimately from two factors: electrical force and diffusion. Electrical force arises from the mutual attraction between particles with opposite electrical charges (positive and negative) and the mutual repulsion between particles with the same type of charge (both positive or both negative). Diffusion arises from the statistical tendency of particles to redistrib… Web17 uur geleden · We recently reported that strong activation of the optogenetic chloride pump, Halorhodopsin leads to a secondary redistribution of K + ions into the cell, through tonically open, leak K + channels.
