Specific channels alter membrane permeability to ions. Semipermeable membranes help create a separation of ions. Electrical charges are separated across the cell membrane. WebB. Porins and ion channels have a permanent hole that passes from one side of the membrane to the other through which solutes pass whereas transporters do not. C. Porins and ion channels mediate passive transport, while transporters are associated with both passive and active transport. Both A and B are correct.
