Chapter 17, Problem 17.96QP

Interpretation Introduction

Interpretation:

The fluid mosaic model of membrane structure should be described.

Concept Introduction:

Cell membrane and plasma membrane: This is the outermost covering of the cell that separates the contents of the cell from its external environment.

The plasma membrane allows or permits the entry and exit of some materials in and out of the cell.

It also prevents movements of some other materials. The cell membrane, therefore is called a selectively permeable membrane.

Biological membrane: Biological membranes are a fluid dynamic closed structure that separates the inside from the outside of cell and compartment within cells.
