Answer:
The correct option is C. Peripheral proteins are not embedded in the lipid bilayer at all.
Explanation:
Option A is correct because trans-membrane proteins are embedded in the lipid bilayer and they control the movement of specific substances in and out of the cell.
Option B is correct because integral membrane proteins have a three-dimensional structure and are permanently embedded in the cell membrane.
Option D is correct because integrins are transmembrane proteins that allow cell adhesion.
Option E is correct because glycoproteins are an important component of the cell membrane as they allow cell to cell adhesion.
Hence, all options are correct except C. Peripheral proteins are not present in the hydrophobic lipid bilayer.
