Globules of up to several thousand amphiphilic molecules arranged with the hydrophilic groups on the surface and the hydrophobic groups buried in the center that form in water are called
A)micelles.
B)liposomes.
C)vacuoles.
D)bilayer membranes.
E)none of the above

Question

Quizplus · Accepted Answer

The description given is characteristic of micelles, which are formed by amphiphilic molecules arranging themselves in a spherical structure with the hydrophilic heads forming the outer surface and the hydrophobic tails buried within the center of the micelle. Liposomes are similar to micelles in composition but have a bilayer membrane structure instead of a spherical shape. Vacuoles are membrane-bound organelles found in eukaryotic cells that have various functions such as storage or waste disposal. Bilayer membranes are similar to liposomes but refer specifically to the double-layered membrane structure found in cells. None of the above options fits the description as accurately as Option A.
