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 requiredflopases-move lipids in reverse comparing to flipases, energy requiredscramblases-no energy required, bidirectional

Because of the action of those proteins, cytosolic side of plasma membrane differs from exoplasmic side (asymmetry).

Nucleic acids

Explanation:

Proteins also contain nitrogen and often sulfur and phosphorus.( SOMETIMES)

but Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P).
