Keeping in view the 'fluid mosaic model' for the structure of cell membrane, which one of the following statements is correct with respect to the movements of lipids and proteins from one lipid monolayer to the other (described as flipflop movement)?
Correct answer: D. While lipids can rarely flip-flop, proteins cannot
- A. While proteins can flip-flop, lipids cannot
- B. Neither lipids, nor proteins can flip-flop
- C. Both lipids and proteins can flip-flop
- D. While lipids can rarely flip-flop, proteins cannot
Explanation
Lipids can flip-flop, they do so slowly with the help of protein called Flippases. But protein do not flip-flop.
