Plasma Membrane Phospholipids

Question

Plasma membrane phospholipids
A) have polar (charged) tails.
B) are arranged in a single layer.
C) have tails that face the exterior of the membrane.
D) are 95% cholesterol.
E) have a hydrophilic head and hydrophobic tails.

Accepted Answer

Phospholipids in the plasma membrane have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails, which is crucial for forming the membrane's bilayer structure, where the heads face the aqueous environments inside and outside the cell, and the tails face each other, away from water.
