Membranes
Membranes are present at the cell surface and also form membranous intracellular organelles, such as RER, mitochondria and vesicles. All membranes consist of a phospholipid bilayer composed of cholesterol and protein; integral membrane proteins span the bilayer; peripheral proteins associate with the membrane surface. Membranes are 8-10 nm in thickness. 45,000x
