Sagot :
Great question! The important component of cell membranes that forms a lipid bilayer with one end able to dissolve in water and the other in fat is a phospholipid.
Phospholipids are a type of lipid molecule that make up the majority of the cell membrane. They consist of a hydrophilic (water-loving) head and two hydrophobic (water-fearing) tails. The hydrophilic head of the phospholipid is attracted to water, while the hydrophobic tails repel water.
When phospholipids come together in the cell membrane, they arrange themselves in a bilayer with the hydrophilic heads facing outward towards the watery environment inside and outside the cell, while the hydrophobic tails face inward, shielded from the water.
This lipid bilayer provides the cell membrane with its characteristic structure and functionality, allowing it to regulate the movement of substances in and out of the cell.
So, the correct answer is b. Phospholipid.
