Question

In fluid mosaic model of plasma membrane:

• A. Upper layer is non-polar and hydrophilic
• B. Polar layer is hydrophobic
• C. Phospholipids form a bimolecular layer in which proteins are embedded
• D. Proteins from a middle layer

Answer 1

The correct option is C Phospholipids form a bimolecular layer in which proteins are embedded

In fluid mosaic model of plasma membrane, phospholipids form a bimolecular layer. The polar hydrophillic heads of the phospholipids lies towards the outer sides of the bilayer and the non-polar hydrophobic tails lie towards the inner side of the bilayer. Proteins are embedded in the bilayer as integral proteins or peripheral proteins.
Thus, option c is correct.
