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.

The electrochemical protection provided to steel by zinc coatings is a vital element in the effectiveness of galvanized coatings in protecting steel from corrosion. All pre-galvanized products rely on the cathodic protection provided by zinc to prevent corrosion of exposed steel at cut edges.ebmaster. Hot dip galvanizing is the process of applying a zinc coating to fabricated iron or steel material by immersing the material in a bath consisting primarily of molten zinc.
