Question

This is an image of the phospholipid bilayer. what are the structures forming the sheets on the outside called (labeled 3)? A. Sodium-potassium pump B. Hydrophobic tail C. helper protein D. Hydrophilic head

Answer 1

The structures forming the sheets on the outside is called Hydrophilic head (Option D).

What is a Hydrophilic Head?

The hydrophilic heads draw water into the membrane, which is subsequently pushed out by the hydrophobic tails. Finally, the water is drawn over the membrane by the second hydrophilic head.

These phrases explain how molecules interact with water since the Greek prefix "hydro" signifies water. The hydrophilic heads are drawn to water andare exposed to the watery environment both within and outside the cell. The heads are composedof a phosphate group that is linked to the tails via a glycerol molecule.
