Which of the following lipid bilayers would have the greates
Which of the following lipid bilayers would have the greatest fluidity and permeability (at room temperature)?
a) A bilayer constructed of saturated phospholipids and fewer cholesterol molecules.
b) A bilayer constructed of unsaturated phospholipids and more cholesterol molecules.
c) A bilayer constructed of saturated phospholipids and more receptor proteins.
d) A bilayer constructed of unsaturated phospholipids and less cholesterol molecules.
e) A bilayer constructed of unsaturated phospholipids, more cholesterol molecules, and more receptor proteins.
Solution
D) A bilayer constructed of unsaturated phospholipids and less cholesterol molecules.... SEEMS TO BE MOST APPARENT ANSWER
LOW UNSATURATED FATTY ACIDS INCREASE FLUDITY .....
CHOLESTEROL ACTUALLY ACTS AS BUFFER INCREASING FLUDITY AT LOW TEMPERATURES AND DECREASING FLUDITY AT HIGH TEMPERATURES ...
