OBS

Ionophores, molecules that carry ions across [mitochondrial], membranes, are essential tools in the study of chemiosmotic mechanisms ... The ionophore valinomy is a cyclic molecule that is soluble in membranes and selectively carries potassium ions (K+). Nigericin also transports potassium, but only in exchange for protons; it is insoluble in the membrane unless one ion or the other is bound.
