According to fluid mosaic model, plasma membrane is composed of:
Correct answer: D. Phospholipids, extrinsic proteins and intrinsic proteins.
- A. Phospholipids and oligosaccharides
- B. Phospholipids and hemicellulose
- C. Phospholipids and integral proteins
- D. Phospholipids, extrinsic proteins and intrinsic proteins.
Explanation
According to the fluid mosaic model, the plasma membrane is a dynamic structure composed of phospholipids forming a lipid bilayer. It also contains integral proteins that are embedded within the lipid bilayer and extrinsic proteins that are loosely attached to the membrane's surface. Together, the phospholipids and proteins form the fluid mosaic pattern, where the proteins float in the lipid bilayer like pieces of a mosaic. Hence, option D is the most appropriate answer.
