Chapter 21, Problem 21.69P

Interpretation Introduction

Interpretation:

A schematic diagram of a lipid bilayer must be drawn. How the bilayer prevents the passage by diffusion of polar molecules like glucose. How non polar molecules like diethyl ether can diffuse through bilayer must be shown.

Concept Introduction:

Cell membranes contain lipid molecules which constitute bilayer. This bilayer has a polar hydrophilic head and non polar hydrophobic tail.
