According to the fluid mosaic model of membrane structure, proteins of the membrane are mostly ________.
A) spread in a continuous layer over the inner and outer surfaces of the membrane
B) confined to the hydrophobic interior of the membrane
C) embedded in a lipid bilayer
D) randomly oriented in the membrane, with no fixed inside-outside polarity

Question

Quizplus · Accepted Answer

The fluid mosaic model describes the plasma membrane structure as a mosaic of components—including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Proteins are embedded in the lipid bilayer, allowing them to move laterally within the membrane. This model emphasizes the flexibility of the membrane and the varied functions of the proteins embedded within it.
