In General,polar Molecules Diffuse More Rapidly Through the Lipid Bilayer

question 45

Multiple Choice

In general,polar molecules diffuse more rapidly through the lipid bilayer part of cell membranes than do nonpolar molecules.This statement is

• A)True
• B)False.Polar molecules diffuse through less rapidly because the bilayer is polar throughout its width
• C)False.Polar molecules diffuse through less rapidly because the bilayer is nonpolar throughout its width
• D)False.Nonpolar molecules diffuse through more rapidly because much of the bilayer is nonpolar
• E)False.The rate of diffusion of nonpolar and polar molecules through the bilayer is essentially the same as long as the molecules are the same size
