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
respects. In this regard, which of the following
statements is incorrect?
(a) Proteins in cell membranes can travel within the
lipid bilayer.
(b) Proteins can also undergo flip-flop movements
in the lipid bilayer.
(c) Proteins can remain confined within certain
domains of the membrane.
(d) Many proteins remain completely embedded
within the lipid bilayer.
