Which of the following statements best describes a characteristic of biological membranes?
A) Phospholipids move laterally within the plane of the membrane.
B) Phospholipids frequently flip-flop from one layer of the membrane to the other.
C) Phospholipids generally occur in an uninterrupted bilayer, with membrane proteins restricted to the surface of the membrane.
D) Phospholipids are arranged with hydrophilic tails in the interior of the membrane.

Question

Quizplus · Accepted Answer

Phospholipids in biological membranes are known for their ability to move laterally within the plane of the membrane, allowing for fluidity and flexibility in the membrane structure. Flip-flopping between layers is rare without the aid of specific enzymes, proteins are embedded within and span the membrane, not just restricted to the surface, and phospholipids are arranged with their hydrophilic heads facing outward and hydrophobic tails facing inward, not the other way around.
