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.

  1. 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, Erwin Nell and Bert zuckerman, won the 1991 Nobel Prize in physiology for their discovery of intracellular ion channels and pioneering of patch clamp techniques.
