Which of the following is a principle of the fluid mosaic model of cell membrane structure?

Question

Quizplus · Accepted Answer

The principle of the fluid mosaic model of cell membrane structure is that phospholipids form a bilayer that is largely impermeable to water-soluble molecules. This allows the membrane to act as a barrier while still allowing small, nonpolar molecules to pass through. The model also describes the presence of proteins, carbohydrates, and cholesterol within the membrane, which contribute to its fluidity and ability to respond to changes in the environment. Option A is incorrect as it describes the structure of phospholipids, but does not relate to the principle of the model. Option B is incorrect as it is a misconception - the lipid bilayer is not solid, but rather exhibits fluidity. Option C is incorrect as it is untrue - some membrane proteins are embedded in the lipid bilayer, while others are anchored to it.
