NEET 2008 Biology question
Keeping in view the 'fluid mosaic model' for the structure of cell membrane, which one of the following statements is correct w.r.t. the movement of lipids and proteins from one lipid monolayer to the other (described as flip-flop movement)?
Answer: (3)
Solution
In the fluid mosaic model, lateral movement of lipids and proteins within a monolayer is rapid, but transverse (flip-flop) movement from one monolayer to the other is very rare for phospholipids and does not occur
