Fluid mosaic model


fluid mosaic model
The currently accepted model of cell membrane structure, which envisions the membrane as a mosaic of individually inserted protein molecules drifting laterally in a fluid bilayer of phospholipids.

(Redirected from Fluid mosaic model)
A component of every biological cell, the selectively permeable cell membrane (or plasma membrane or plasmalemma) is a thin and structured bilayer of phospholipid and protein molecules that envelopes the cell.

Describe the most recent version of the fluid mosaic model of membrane structure.
Molecules moving to regions where they are less concentrated are moving down their concentration gradient.

fluid mosaic model A model proposed by Singer and Nicholson, describes biological membranes as a fluid lipid bilayer with embedded proteins creating a mosaic.

Such movement can be described by the Fluid Mosaic Model, which describes the membrane as a "mosaic" of lipid molecules that act as a solvent for all the substances and proteins within it, ...
