State the different structural features of the cell membrane.
Phospholipids, cholesterol, channel and carrier proteins, receptor proteins, glycoproteins and glycolipids.
Describe the phospholipid bilayer.
The hydrophilic heads of the phospholipids form the inner and outer surface of the membrane and the hydrophobic tails form the inside of the membrane.
What is the function of the phospholipid bilayer?
The surface of the membrane can interact with water inside and outside the cell, but water-soluble substances cannot diffuse through the hydrophobic core.
Describe the structure of the cell membrane.
The structure of the cell membrane is described by the fluid mosaic model. The cell membrane is made up of many structures that are constantly moving within the bilayer
What is embedded between the phospholipids to prevent too much movement?
