Cell Membrane Structure & Functions:
The cell membrane makes the outer wall of the cell. The central lipid bilayer is made up mainly of phospholipids and cholesterol. Its fluidic in nature and permeable to only lipid and lipid soluble substances. Attached to the lipid bilayer are proteins that serve as transport proteins, receptors, second messengers, enzymes, adhesion molecules, submembrane cytoskeleton and antigen. And we also have carbohydrates, making outer coat, called glycocalyx. The carbohydrates give the cell surface negative charge, help one cell to attach to the other, serve as receptor and participate in immune functions.
