Lipid molecule in plasma membrane are arranged in
Open in App
Solution
The correct option is D Head parallel
- Lipid molecules in the plasma membrane form a bilayer with hydrophobic tails buried inside the central region and hydrophilic heads towards the two surfaces.
- According to the fluid mosaic model of Singer and Nicolson, cell membranes are quasi-fluid in nature with a viscous lipid bilayer having proteins at places (mosaic) both on the surface and inside.
- The arrangement of lipids in the bilayer is also called head parallel arrangement because the polar heads of both the lipid layers are oriented on the surface and hydrophilic tails are embedded towards the inside of the membrane.
So, the correct answer is 'Head parallel'
