Solution
The correct option is D Both Assertion and Reason are incorrect
- Peripheral protein, or peripheral membrane proteins, are a group of biologically active molecules formed from amino acids which interact with the surface of the lipid bilayer of cell membranes. Unlike integral membrane proteins, peripheral proteins do not enter into the hydrophobic space within the cell membrane. Instead, peripheral proteins have specific sequences of amino acids which allow them to attract to the phosphate heads of the lipid molecules or to integral proteins.
- Integral proteins are embedded within the lipid bilayer.
So, the correct answer is 'Both Assertion and Reason are incorrect'.
