According to the fluid mosaic model of cell membranes, which of the following is a true statement about membrane phospholipids?

Question

Quizplus · Accepted Answer

According to the fluid mosaic model, membrane phospholipids can move laterally along the plane of the membrane. This lateral movement is essential for the membrane's flexibility and integrity. However, they are restricted from flipping-flopping from one side of the membrane to the other, as it requires energy and the assistance of specific enzymes. Additionally, the model suggests that the membrane is not an uninterrupted bilayer but rather a dynamic structure with various proteins and other molecules embedded within the lipid bilayer. Lastly, membrane phospholipids are not free to depart from the membrane and dissolve in the surrounding solution, as they are held together by hydrophobic interactions within the hydrophobic tails of the bilayer.
