Vedclass · Answer

(B) According to the fluid mosaic model,the plasma membrane is a fluid structure. Lipids can move laterally within the membrane,and they can also undergo 'flip-flop' movement (transverse diffusion) from one leaflet to the other,although this process is slow and often requires enzymes called flippases. Proteins,due to their large size and amphipathic nature,are generally unable to undergo flip-flop movement across the lipid bilayer. Therefore,lipids can occasionally exhibit flip-flop movement,but proteins do not.

Considering the fluid mosaic model of the plasma membrane,which of the following statements is true regarding the movement of lipids and proteins from one monolayer to the other? (The movement is described as flip-flop.)
