What is the function of the cell membrane?
The primary function of the cell membrane is the encapsulation of the cell content. It contains all cell structures in it. His secondary functions include the regulation of what molecules and substances can enter and step out of the cell and its water balance. Its basic functions are similar to the functions of the medieval city walls surrounding the city.
Prokaryotic and eukaryotic cells have small differences in their membrane structures, but the function of the cell membrane has not changed. The basic structure of the membrane or plasma consists of proteins and lipids. The membrane is basically two layers of phospholipids delayed back on their backs to join their tails together. The internal and outer surfaces of the membrane are mostly formed by phospholipid heads. Surfaces are occasionally punctuation channels creating proteins or trans-membrane proteins and peripheral proteins.
The first function of the cell membrane is to contain cytoplasm. This includes liquid cytosol, nucleic friendrial such as deoxyribonucleic acid (DNA) and howAny organelles such as mitochondria. It also anchor the cell to the cell wall and the surrounding tissues to make the shape of the cells. Three of these means are passive and two are active. Passive means of transport are diffusion of lipids, osmosis and passive transport. Two active means are active transport and vesicles.
Lipid diffusion occurs when a certain type of lipids encounters a cell membrane. Molecules of soluble lipids such as steroids are able to distract the membrane. In these cases, it is as if the membrane did not exist.
The function of the cell membrane almost does not exist almost during osmosis. Osmosis is the movement of water in and out of the cell. This movement of water naturally attempts to balance the concentration of water solution. If there are too many solutes in the solution, such as proteins, water from a less concentrated area naturally moves to a densely concentrated solution.
passive transportAnd active transport rely on proteins in the lipid membrane. During passive transport, certain molecules may diffuse trans-mangean proteins without activation or invitation. When the cell requires some molecules to bring to the cell, then active transport uses the protein pump and enzyme molecule.
vesicles are another way to bring specific molecules to the cell, but without the use of protein to do so. The molecule connects to the cell membrane and then closes the membrane around the molecule. This closed molecule is called vesicles. The vesicles are separated from the membrane so that it is inside the cell where it spends the molecule and releases its components into the cytoplasm.
