According to 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 repects. In this regard, which of the following statements is incorrectA. Proteins in cell membranes can travel within the lipid bilayerB. Proteins can also undergo flip-flop movements in the lipid bilayerC. Proteins can remain confined within certain domains of the membraneD. Many proteins remain completely embedded within the lipid bilayer |
