Singer and Nicolson's Fluid Mosaic Model of the Membrane Proposed

Question

Singer and Nicolson's fluid mosaic model of the membrane proposed that
A) membranes are a phospholipid bilayer.
B) membranes are a phospholipid bilayer between two layers of hydrophilic proteins.
C) membranes are a single layer of phospholipids and proteins.
D) membranes consist of protein molecules embedded in a fluid bilayer of phospholipids.
E) membranes consist of a mosaic of polysaccharides and proteins.

Accepted Answer

Singer and Nicolson's fluid mosaic model proposed that membranes consist of protein molecules embedded in a fluid bilayer of phospholipids. This model suggests that the membrane is not a static structure, but rather a dynamic and fluid entity in which molecules are constantly moving and interacting with each other. This model has been supported by numerous experimental studies and remains a widely accepted model of the cell membrane.
