The lipid bilayer molecules do what for the cell?

Answer 1

The lipid bilayer molecules act as a barrier for the cell.

Lipoprotein bilayer molecules function as a barrier, permitting only specific molecules or substances to penetrate the bilayer and enter the cell, and vice versa. The lipid bilayer is made up of two "layers": the hydrophilic (or water-loving) "head" part of the bilayer, which is circular in shape, and the hydrophobic (or "stringy") "tail" part of the bilayer, which is rectangular in shape.

Lipid bilayer molecules constitute the fundamental building blocks of cell membranes, establishing a wall that divides the inside of the cell from the outside world. They control the flow of molecules into and out of the cell, preserving homeostasis and permitting cellular functions.
