Consider the Concentration Gradient (A) and Electrochemical Gradient (B) figures below. In The Concentration Gradient (A) scenario, the extracellular solutes (i.e., the solutes in the blue box outside of the cell) would the cell. In the Electrochemical Gradient (B) scenario, the solutes would move the negative charge.
