Question

The plasma membrane is composed of phospholipids, which are free to move laterally, and is peppered with both stationary and mobile proteins. This view of the plasma membrane is known as the:

Answer 1

Answer;

-Fluid mosaic model

Explanation;

-The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components; including phospholipids, cholesterol, proteins, and carbohydrates; that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness.

-The Fluid Mosaic Model states that membranes are composed of a Phospholipid Bilayer with various protein molecules floating around within it. The Fluid part represents how some parts of the membrane can move around freely, if they are not attached to other parts of the cell. The mosaic part illustrates the ‘patchwork’ of proteins that is found in the Phospholipid Bilayer.
