plasmamembrani
Plasmamembrani, also known as plasma membranes or cell membranes, are the outer boundaries of all living cells. They are composed of a phospholipid bilayer, which provides a fluid and semi-permeable barrier that regulates the movement of substances into and out of the cell. The phospholipid bilayer consists of two layers of phospholipid molecules, with their hydrophilic (water-loving) heads facing outward and their hydrophobic (water-fearing) tails facing inward.
Embedded within the phospholipid bilayer are various proteins and carbohydrates, which serve different functions. Integral proteins
