WebWhen transition metal ions are in aqueous solution, they will have water molecules as ligands. For example, Cu2+ (aq) will involve the complex ion [Cu (H2O)6]2+. The water molecules can be replaced by other ligands. For example, chloride ions can be added to the solution and the chloride ions will replace the water molecules as ligands. WebWhen a ligand binds to the extracellular region of the channel, there is a conformational change in the proteins structure that allows ions such as sodium, calcium, magnesium, and hydrogen to pass through ( [link] ). Gated ion channels form a pore through the plasma membrane that opens when the signaling molecule binds.
