If free phospholipids were swirled into water, they would ____.
A)form pairs
B)form spheres with the phosphate-containing heads facing each other
C)dissolve
D)form a lipid bilayer sheet, with the hydrophobic tails facing each other
E)form a lipid bilayer sheet, with the phosphate-containing facing each other

Question

Quizplus · Accepted Answer

Free phospholipids have a hydrophilic head and a hydrophobic tail. When swirled into water, they will arrange themselves to minimize interactions with water molecules. One way to do this is by forming a lipid bilayer sheet, with the hydrophobic tails facing each other and the hydrophilic heads facing towards the water. This is the structure found in cell membranes.
