They are relatively rigid structures d. They are composed of two leaflets of phospholipids e. They function to separate the extracellular andintracellular environment Which of the followoing statements about plasma membranes isINCORRECT? a. They are composed of phospholids b.

Explanation / Answer

      c. They are relatively rigidstructures           Plasmamembrane is a combination of proteins (which are both integral andperipheral) and phospholipids.           It iscomposed of two leaflets of phospholipds and separate theextracellular and intracelular environment.           Hence,these 4 options are ruled out.           Plasmamembrane is not rigid instead it is a fluid type.           Thebestmodel is the fluid mosaic model.
