Each of which is specific for a specific ion. All these reflect the basic structure of the aqueous pore which allows a particular ion to pass through it.
Like the front door of a fence that can be opened or closed,
Most are through ion channels: they can be blocked by the ion pathway
or unlocked. Gateway channel opens when something happens
to change the shape of the protein.

Depending on the channel, this excitation can range from binding to chemical
An indication of electric charge due to an imbalance of ions.
Once the channel opens, millions of ions can flow through it
how fast per second, in which direction
(inside or outside the cell), depending on the slope of the ion concentration between the cell’s cytoplasm and the external environment.

For example, if the concentration
Potassium ion (K+) is larger than inside the cell, K+ enters the cell through potassium channel
; If the concentration inside the cell is high, it is K+. Is
spreads out of the cell.

How does an ionic channel show its specificity to an ion?
And others aren’t? It is not a matter of fee or amount.
For example, K + .
