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.

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.The whole process makes sheet iron last much longer.xists and is an alternate of. Merge this question into.

Zinc metal does not react violently with water. It hardly oxidises under normal conditions. A coating of zinc (called galvanising) is used to protect steel from rusting.Zinc has a coating of the oxide that protects it from reaction with oxygen.It becomes vulnerable to oxidation in the presence of other substances that weaken its oxide layer. Acids will quickly dissolve zinc, as will alkalies. Acids produce zinc 2+ cations, whereas alkalies produce zincate ZnO2(2-) anions.inc has a coating of the oxide that protects it from reaction with oxygen.
