and their sugar groups are exposed at the cell surface.
8. Trans-membrane proteins typically span the lipid bilayer in an _______________ configuration. The
amino acids that pass through the bilayer tend to have _____________________ side chains.
3. Proteins that extend across the bilayer and are exposed to an aqueous environment on both sides of the membrane are called ___________________________ proteins.
Explanation / Answer
2. Sugar-containing lipids called GLYCOLIPIDS are found only in the outer half of the bilayer
and their sugar groups are exposed at the cell surface.
8. Trans-membrane proteins typically span the lipid bilayer in an beta configuration. The
amino acids that pass through the bilayer tend to have POLAR ,HYDROPHILLIC side chains.
3. Proteins that extend across the bilayer and are exposed to an aqueous environment on both sides of the membrane are called INTEGRAL proteins.
