An Overall View An action potential is produced by the movement ofions across the membrane through voltage-gated chan-nels. This ion movement, which occurs only when thechannels are open, changes the distribution of chargeson either side of the membrane.
Galvanising is a term used to describe the protection of a metal (usually iron or steel) by the application of a Zinc coating.

Answer by Robbb. Confidence votes 86.8K. Zinc is used in galvanizing because zinc can be made to stick to iron and does not rust. In addition, when you cut it, the zinc will cover the iron at the point where it is cut.
Galvanizing is the practice of immersing clean, oxide-free steel into molten zinc to from a protective coating over the metal. The coating is bonded metallurgically to the steel and this coating helps to protect the surface against corrosion.In recent use, the term refers to the coating of steel or iron with zinc. Electro-Galvanizing: It is an electrolytic process for galvanizing, where a thinner, tighter bonding coat of zinc is applied to a metal through âelectroplatingâ. 2  Electro plating is a process of running a current of electricity through a saline/ zinc solution with a zinc anode and steel conductor.
