Question

According to the fluid mosaic model of cell membranes, phospholipids ________.


occur in an uninterrupted bilayer, with membrane proteins restricted to the surface of the membrane


have hydrophilic tails in the interior of the membrane


can move laterally along the plane of the membrane


frequently flip-flop from one side of the membrane to the other

Answer 1

Answer:

They frequently flip-flop from one side of the membrane to the other.

Answer 2

According to the fluid mosaic model of cell membranes, phospholipids frequently flip-flop from one side of the membrane to the other.

What do you mean by the Fluid mosaic model?

The fluid mosaic model may be defined as the model of the plasma membrane that consists of two-layer of lipids and proteins molecules are embedded among the lipid bilayer.

Phospholipids have a hydrophobic tail which is found in the interior of the membrane, while a hydrophilic head is found on the outer side of the membrane.

These molecules frequently flip-flop from one side of the membrane to the other with the help of flippase, floppase, and scramblase.

Therefore, it is well described above.
