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 statement is incorrect? |
|
|
a) |
Proteins in cell membranes can travel within the lipid bilayer |
|
b) |
Proteins can remain confined within certain domains of the membrane |
|
c) |
Proteins can also undergo flip-flip movements in the lipid bilayer |
|
d) |
Many proteins remain completely embedded within the lipid bilayer |
