The endoplasmic reticulum helps in the manufacture of fat molecules or lipids. These proteins and lipids help in the building of the cell membrane. This process is known as membrane biogenesis.
An integral membrane protein that spans the entire cell membrane, from the outer surface of the cell to the inner surface of the cell, is called a transmembrane protein. A peripheral membrane protein that resides on the outer surface of the cell membrane interacts with molecules that are ...
Plant cells, on the other hand, have a cell wall in addition to the cell membrane. Here, the cell wall is exterior to the cell membrane (the cell membrane lies beneath the cell wall) and thus surrounds the entire cell including the membrane. ...
The cell membrane is sometimes also referred to as the plasma membrane. Cell membranes are based on a framework of fat-based molecules called phospholipids, which physically prevent water-loving, or hydrophilic, substances from entering or escaping the cell. These membranes are also studded with ...
