Which of the following would be the most energetically unfav

Which of the following would be the most energetically unfavorable membrane lipid movement in a membrane?

1) Movement between monolayers

2) Rotation

3) Vibration

4) Lateral diffusion in the monolayer

Solution

1) Movement between monolayers

phospholipid molecules in synthetic bilayers very rarely migrate from the monolayer on one side to that on the other.
