Ion Channel
When living cells continue to carry out metabolic activities, they must constantly exchange substances with the surrounding environment. The ion channels on the cell membrane are an important way to exchange such substances. It is known that most important substances to life are water-soluble, such as various ions, and sugars, they need to enter the cell, and the water-soluble waste generated in life activities also leaves the cell.

Ion Channel
When living cells continue to carry out metabolic activities, they must constantly
exchange substances with the surrounding environment. The ion channels on the cell
membrane are an important way to exchange such substances. It is known that most
important substances to life are water-soluble, such as various ions, and sugars, they
need to enter the cell, and the water-soluble waste generated in life activities also
leaves the cell.
The channel which they enter is the ion channel on the cell membrane. Ion channels
are composed of special proteins produced by cells, and are gathered and embedded
in the cell membrane, forming pores occupied by water molecules. These pores are
the channels which water-soluble substances can enter and exit the cells quickly. The
activity of the ion channel is that the cells regulate the entry and exit of the
corresponding substance through the opening and closing of the ion channel, and
are important for achieving various functions of the cell. Two German scientists,
