Question

Which moleclues prevents cell membranes from Dissvoling in water?

Answer 1

Nonpolar Fatty Acids

Answer 2

Answer:lipid molecules

Explanation:

lipid molecules prevent membrane from dissolving and they are also known as phospholipids.

A lipid molecule could be imagined as rectangle. With one end i.e the bottom of the lipid molecule that is hydrophilic which means they are water-loving.

The other end of the head of the lipid molecule which is hydrophobic, which is the non-polar and water-fearing end of the molecule.

Within protective layer surrounding the outside cell(Cell membrane) there are large amounts of lipid molecules. Phospholipids are the most abundant that prevent membrane from dissolving.

Water is a polar solvent and prefers dissolving polar molecules such as salt but Lipids is a non polar molecule and can't be dissolved by water the presence in abundance prevents dissolution.
