The statements that describe how the trans bilayer asymmetry in the lipid bilayer is achieved and maintained are listed below.
Explanation:
Phospholipids in the plasma membrane are anchored to a specific location in the plasma membrane via strong hydrophobic interactions with neighbouring lipids thus maintaining the asymmetrical distribution of lipids in the bilayer.
Specific phospholipids in the plasma membrane covalently attach to certain integral membrane proteins.These covalent interaction anchor the phospholipid to specific location in the plasma membrane and maintain the asymmetrical distribution of lipids in the bilayer.
