Here is a question I found:
Which of the following factors does NOT affect membrane permeability?
A. Temperature
B. The saturation of hydrocarbon tails in membrane phospholipids
C. The amount of cholesterol in the membrane
D. The polarity of membrane phospholipids
E. They all affect membrane permeability

A through C all affect membrane fluidity, and to me it seems that the more fluid a membrane is, the more permeable it will be. I'm not sure how polarity of membrane phospholipids would do anything... so I'd say D. Any thoughts?
