or an uncharged molecule, the direction of passive transport across a membrane is determined solely by its gradient - For a charged molecule, the direction of passive movement must also be considered by . - The net driving force for a charged molecule across a membrane therefore has two components and is referred to as the gradient. - The transporter proteins called use the movement of one solute down its gradient to provide the energy to drive the uphill transport of a second solute.
