Vedclass · Answer

(B) According to the Fluid Mosaic Model,lipids and proteins are dynamic within the membrane. However,protein molecules do not exhibit 'flip-flop' movement (transverse diffusion from one leaflet to the other) within the lipid bilayer. This is because proteins are large in size and possess hydrophilic regions that would need to pass through the hydrophobic core of the lipid bilayer,which is energetically unfavorable. Therefore,statement $B$ is incorrect.

The most accepted Fluid Mosaic Model describes the cell membrane as a quasi-fluid structure where lipids and integral proteins are arranged in a mosaic pattern. In recent years,this model has been refined. Which of the following statements is incorrect regarding this model?
