Keeping in view the ‘Fluid mosaic model” for the structure of cell membrane, the movement of lipids and proteins from one lipid monolayer to the other, lipid can rarely flip-flop, protein can not. The fluid mosaic model is the most important and widely accepted latest model for plasma membrane was given by Singer and Nicolson in 1972. According the them it is “ protein iceberg in a sea of lipids”.

Answer:
Introduction to the Fluid Mosaic Model:
The fluid mosaic model is a widely accepted model that describes the structure and organization of the cell membrane. According to this model, the cell membrane is composed of a phospholipid bilayer with embedded proteins. The phospholipids are arranged in two layers, known as lipid monolayers, with their hydrophilic heads facing outward and their hydrophobic tails facing inward. The proteins are embedded within the lipid bilayer and can have various functions, such as transport, signaling, and structural support.
Flip-Flop Movement:
The flip-flop movement refers to the lateral movement of lipids and proteins from one lipid monolayer to the other. In other words, it involves the movement of a lipid or protein molecule from the outer layer of the lipid bilayer to the inner layer, or vice versa.
Can Lipids Flip-Flop?
Lipids, specifically phospholipids, are the major components of the cell membrane. They have a hydrophilic head and a hydrophobic tail, which gives them the ability to form a stable bilayer structure. However, due to the hydrophobic nature of the lipid tails, the flip-flop movement of lipids is energetically unfavorable and occurs at a very slow rate. Therefore, lipids rarely undergo flip-flop movement.
Can Proteins Flip-Flop?
Proteins, on the other hand, are diverse and complex molecules that perform various functions in the cell membrane. Unlike lipids, proteins have a hydrophilic exterior and a hydrophobic interior, which allows them to be embedded within the lipid bilayer. Some proteins are anchored to the membrane through their hydrophobic regions, while others span the entire lipid bilayer. Therefore, proteins have the ability to undergo flip-flop movement.
Conclusion:
In conclusion, based on the fluid mosaic model for the structure of the cell membrane, the correct statement regarding the flip-flop movement is that while lipids can rarely flip-flop, proteins can undergo flip-flop movement. Lipids have a stable bilayer structure and their hydrophobic tails make the flip-flop movement energetically unfavorable. On the other hand, proteins have diverse structures and functions, allowing them to be embedded within the lipid bilayer and undergo flip-flop movement.
