Vedclass · Answer

(B) The correct answer is $(b)$.According to the fluid mosaic model, while lipids and proteins exhibit lateral diffusion (moving within the plane of the membrane), proteins do not undergo flip-flop movements (transverse diffusion) across the lipid bilayer due to their large size and polar nature.Option $(a)$ is correct because proteins can move laterally within the lipid bilayer.Option $(c)$ is correct because certain proteins are restricted to specific domains (e.g., lipid rafts or specific cell surfaces) to perform localized functions.Option $(d)$ is correct because integral proteins can be completely embedded within the lipid bilayer (non-transmembrane proteins).

According to the widely accepted "Fluid mosaic model", cell membranes are semi-fluid, where lipids and integral proteins can diffuse randomly. In recent years, this model has been modified in several respects. In this regard, which of the following statements is incorrect?
