Question

Problem 5

Answer 1

Background and context

Two layers of lipids make up the phospholipid bilayer. A hydrophobic tail and a hydrophilic head are found on each lipid. The hydrophobic tails face the inner side of the bilayer, forming a hydrophobic area kept in place by intermolecular interactions between tails. The movement of the membrane caused by the viscosity of the phospholipid composition is known as membrane fluidity.
