The gradients of the other ions are most likely accounted for by Cotransport protein. The movement of the majority of the ions takes place by the phenomenon of electrochemical gradients.
electrochemical gradients of which some are found on the surface of the membrane and function as electrogenic pumps. While the gradients of some of the ions are mostly accounted for by the co - transport proteins, as these proteins take part in the movement of ions or molecule through a plasma membrane that involves concentration gradient based on the kind of molecules and movement.
