Multiple Choice
Which of the following is true of the fluid mosaic model of membrane structure?
A
Proteins are embedded in a phospholipid bilayer and can move laterally within the layer.
B
Carbohydrates form the main structural component of the membrane.
C
Proteins are fixed in place and do not move within the membrane.
D
The membrane is composed solely of a rigid layer of phospholipids.
Verified step by step guidance1
Understand the fluid mosaic model: The fluid mosaic model describes the structure of cell membranes as a dynamic and flexible arrangement of molecules.
Identify the components of the membrane: The membrane is primarily composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates.
Recognize the role of phospholipids: Phospholipids form a bilayer that provides the basic structure of the membrane, allowing it to be fluid and flexible.
Examine the behavior of proteins: Proteins are embedded within the phospholipid bilayer and can move laterally, contributing to the fluid nature of the membrane.
Clarify the role of carbohydrates: Carbohydrates are attached to proteins and lipids on the extracellular surface of the membrane, playing a role in cell recognition and signaling, but not as the main structural component.
