NEET 2002 Biology question

In fluid mosaic model of plasma membrane

(1)Upper layer is non-polar and hydrophilic
(2)Polar layer is hydrophobic
(3)Phospholipids form a bimolecular layer in middle partCorrect
(4)Proteins form a middle layer

Answer: (3)

Solution

In the Singer-Nicolson fluid mosaic model the plasma membrane is a quasi-fluid phospholipid bilayer (bimolecular layer) in which proteins are embedded or float like icebergs. The hydrophilic polar heads face outwards, while the hydrophobic non-polar fatty-acid tails face each other in the
