Question

The Fluid Mosaic Model is a biological model that describes the structure and function of the plasma membrane. The term "fluid" in the name of this model suggests something about the nature of the membrane.

A. The plasma membrane is a liquid, or fluid. B. Anything can pass through the membrane. C. Components of the membrane can move and shift. D. The addition of cholesterol destabilizes the membrane, turning it into a liquid.

A. While it is true that the plasma membrane has a fluid-like quality, it is not accurate to say that it is a liquid. B. This answer is incorrect because the plasma membrane is selectively permeable, meaning that not just anything can pass through it. C. This answer is the most accurate. The fluidity of the plasma membrane refers to the ability of its components to move and shift within the plane of the membrane. D. While the addition of cholesterol can affect the fluidity of the membrane, it does not turn it into a liquid.
