First 161 words of the document:

Cell membrane:
Phospholipid bilayer: forms the basic structure
Cholesterol: gives the membrane of some eukaryotic cells mechanical stability (membrane stability
and fluidity)
Channel protein: allow the movement of some substances across the membrane. Too large and too
water loving (hydrophilic) travel through here. (Transport)
Carrier proteins: actively move substances across the membrane. (Transport)
Receptor sites: some allow hormones to bind with the cell so that a cell response can be carried out.
(Recognition and communication). Cell membrane receptors are also important in allowing drugs to
bind.
Glycoproteins: involved in cell signalling that they are self to allow recognition by the immune system.
They can also bind cells together in tissues, can also be hormone receptors
Glycolipids: involved in cell signalling that they are self to allow recognition by the immune system,
can also be hormone receptors
Enzymes and coenzymes: for metabolic processes
