Freeze fracture is a technique used to visualize membrane proteins. In this technique, cells are rapidly frozen and then split, separating the lipid bilayer into its two component layers. Transmembrane proteins stay associated with one layer and leave a pit in the other. The fluid mosaic model predicts what kind of pattern of proteins and pits?
A)a random arrangement of proteins and pits
B)a random arrangement of proteins, but an ordered arrangement of pits
C)an ordered arrangement of proteins, but a random arrangement of pits

Quizplus · Accepted Answer

The fluid mosaic model of the cell membrane describes the membrane as a fluid combination of lipids, proteins, and carbohydrates. Proteins are distributed randomly in this model, leading to a random arrangement of proteins and pits when observed through freeze fracture techniques.
