Question
Chapter 20.4, Problem 7P
Interpretation Introduction
Interpretation:
The way in which the bacteria regain their original fluidity has to be given.
Concept Introduction:
Phosphoglycerides form membranes by arranging themselves in a lipid bilayer.
The polar heads of the phosphoglycerides are on both surfaces of the bilayer and fatty acids form the interior of the bilayer.
