What does the lipid bilayer molecules do?

Answer 1

The lipid bilayer that forms the cellular membrane forms an effective semi-permeable membrane. The lipid bilayer typically can typically exclude larger molecules based on size (molecular weight) and other molecules based on charge (ions and salts).

Answer 2

The molecules that make up the cell membrane are phospholipids. A phospholipid has a hydrophobic "water hating" tail and a hydrophylic "water loving" head. When exposed to a polar solution, such as water or cytoplasm or extracellular fluid, the phospholipids arrange themselves into a lipid bilayer because it is energetically favourable to have the hydrophobic tails "shielded" from the polar solution.

Answer 3

The phospholipid bilayer only lets small, uncharged molecules in due to its hydrophobic inside. In addition, they don't let materials that are unsoluble in lipids inside.

Answer 4

The lipid bilayer forms because there is water both inside and outside of the cell.

Answer 5

because lipid act as regulatory unit for influx and outflux of ions or any components within or outside,the cell

Answer 6

The Lipid Bilayer of membranes form a barrier to molecules because it is comprised of non-polar phospholipids, which let only small non-polar or lipid soluble molecules to enter.
