The English translation of the given question is given below:
what is the structure of the plasma membrane?
Answer:
The plasma membrane is a biological membrane that separates the interior of all cells from their external environment
The plasma membrane has fluid mosaic structure composed of lipids, proteins and carbohydrates.
The membrane is partially made up of molecules called phospholipids and is bilayer phospholipid membrane, which consists of two non-polar, hydrophobic tails arranged on the inside and one polar, hydrophilic heads attached with phosphate group arranged on the outside.
Proteins in plasma membrane are divided into two types peripheral and integral membrane proteins. Peripheral membrane proteins are present at inside or outside of the membrane while integral membrane proteins are integrated in the membrane and are attached to hydrophobic regions.
Carbohydrates in plasma membrane are attached at the outside of the cellular membrane, facing away from the cell.
