What is the Cell membrane?

The cell membrane is also called the plasma membrane. It is a biological membrane that separates the interior of cells from the outside environment, which protects them from the environment. The cell membrane is active and an important part of the body. It contains membrane proteins which include integral proteins which serve a membrane transporters and peripheral proteins.

The membrane also controls the movement of substances in and out of the cells. The cell membrane primarily has fatty acid-based lipids and proteins. These lipids are divided into two types which are phospholipids and sterols. The cell membrane gives an immediate response to the stimulus by creating a change in membrane potential.

The cell membrane is a wafer-thin layer that contains every living cell, delineating the cell from the environment that surrounds it. Walled by this cell membrane are the cell’s components that are water-soluble and often highly charged.

In the surrounding water-based environment, outside the cell are ions, acids, and alkali that are toxic to the cell and nutrients that the cell must absorb to thrive. The cell membrane has two functions: first, to be a barrier, maintaining the parts of the cell and discarded substances as a gate permitting transport into the cell of vital nutrients and the ridding the cell of waste.

Cell membranes are made of mostly fatty acid-based lipids and proteins. Membrane proteins are also two types, with one type being extrinsic proteins and intrinsic proteins. The chemical formation of the cell membrane makes it the perfect place for growing and dividing cells.

The cell membrane is known to be the part of the cell that will separate the inside portion of the cell from the external environment. The cell membrane will contain a lipid bilayer which will also have some cholesterols that will ensure that the cell will continue to stay fluid no matter what the current temperature is.

The cell membrane will also have some other functions. For example, this is also in charge of transporting the different nutrients that it receives to the rest of the cell so that it will be properly nourished. This will also be in charge of transporting the different substances that are toxic to the cell.
