Most channels are made of specialized transmembrane proteins.
In the membrane of a cell, channels serve as passageways.
The "cell membrane" is the cell that is embedded with channels.

The cell membrane controls what enters and leaves the cell. There are protein channels within the lipid bilayer (membrane) of the cell. There are carbohydrate chains that hang off of the protein channels that identify each particle around the cell to make sure its what the cell needs, if not it wont let it in.
An animal Cell membrane is made up of phospholipids (main bulk of membrane), Proteins, protein channels and Cholesterol. Protein parts main role is for structure and the protein channels allow active transport of molecules in or out of the cell. The Phospholipids however are semi permiable and so also allow some materials in and out of the cell too. Cholesterol is involved with the fluidity of the cell membrane. Hope this helps. :o)
