Answer:
A. play a role establishing and maintaining membrane lipid asymmetry
Explanation:
Proteins that move move certain phospholipids between leaflets are transmembrane proteins via "flip-flop" transition have also the possibility to maintain membrane lipid asymmetry. There are few types of such proteins:
- flipases-move lipids from the exterior to the interior side of the membrane, energy required
- flopases-move lipids in reverse comparing to flipases, energy required
- scramblases-no energy required, bidirectional
Because of the action of those proteins, cytosolic side of plasma membrane differs from exoplasmic side (asymmetry).
It is always working.
It even works while the person is sleeping to push saliva down the throat.
