Document Summary
Amount of cholesterol if the membrane is getting to rigid, they move in between and vice versa. Peripheral membrane proteins associate non-covalently with the surfaces of the lipid bilayer. Lipid-anchored proteins are covalently attached to lipids in the bilayer. 5. any substance that can bind to a specific molecule (ligand), often leading to uptake or signal transduction. Ldl receptors are integral membrane proteins found on the plasma membranes of cells. Highly conserved glycoproteins a protein combined with a sugar group. Contain a single transmembrane domain slide 2. Ldl receptors on the cell surface bind to ldl particles in the blood. Ldl is brought into the cell by endocytosis. The ldl recepotor brings cholesterol into the cell by endocytosis.
