Multiple Choice

Explain how the fluid mosaic model of the cell membrane supports its function in regulating the internal environment of the cell. Consider the arrangement and movement of molecules within the membrane.

• The model suggests a rigid structure where molecules are fixed, preventing any substance from entering or leaving the cell.

• The model depicts the membrane as a dynamic structure with proteins and lipids that move laterally, allowing selective permeability and fluidity.

• It proposes that the membrane is completely permeable to all molecules, which helps in the unrestricted exchange of substances.

• The model indicates that the membrane is impermeable, enhancing the cell's ability to maintain a stable internal environment by isolation.
