According of fluid mosaic model, plasma membrane is composed of
-
- phospholipids and oligosaccharides
- phospholipids and hemicellulose
- phospholipids and integral proteins
- phospholipids, extrinsic proteins and intrinsic proteins
Correct Option: D
According to fluid mosaic model proposed by Singer and Nicolson (1972, 74), plasma membrane is composed of a phospholipid bilayer and protein. Protein molecules occur at places both inside and outside of lipid bilayer. The internal proteins are called intrinsic proteins and the external proteins are called extrinsic proteins.
