the cell membrane is composed of carbohydrates, proteins, and phospholipids. The proteins act as transport molecules to move material in and out of the cell (kind of like a tunnel). They are embedded in the membrane. These proteins are needed due to the phospholipid bilayer. The inside of the bilayer repels water, so this keeps all materials out of the cell unless it has been selected to be carried in by the proteins. The carbohydrates are located on the outside of the membrane. They recognize things the cell may need. For instance, ADH (Anti-diuretic hormone) is only needed in the kidneys, so the carbohydrates only recognize it there.

The cell is the structural, functional, and biological unit of all organisms. It is a membrane-bound structure containing cytoplasm and cytoplasmic structures. The membrane that surrounds the cell and separates it from the outside environment is the cell membrane whereas a cell wall is another structural layer surrounding the cell, next to the cell membrane. visit our page : womenwhowin100 .com/women-entrepreneurs
