Question

How is the fluid mosaic model described?

Answer 1

Fluid mosaic model:

1. The fluid mosaic model is a model that explains the structure of the plasma membrane of an animal cell.
2. This model was proposed by Singer-Nicholson in 1972.
3. According to the fluid mosaic model, a plasma membrane consists of sheet-like structures that are made up of proteins and lipids.
4. The lipids are arranged in a double-layer or bilayer and the proteins are distributed in the bilayer.
5. Intrinsic and extrinsic proteins are present. The intrinsic proteins are embedded in the lipid bilayer whereas extrinsic proteins are present outside of the lipid membrane.
