Multiple Choice

The fluid mosaic model of the membrane proposed that membranes:

Consist of a single layer of phospholipids and proteins.

Consist of a phospholipid bilayer composed of a variety of fatty acids.

Consist of protein molecules embedded in a dynamic bilayer of phospholipids.

Consist of a phospholipid bilayer between two layers of hydrophilic proteins.

Verified step by step guidance

Understand the fluid mosaic model: It describes the structure of cell membranes as a dynamic and flexible arrangement of lipids and proteins.

Recognize the key components: The model suggests that membranes consist of a phospholipid bilayer with embedded proteins, allowing for fluidity and movement.

Identify the phospholipid bilayer: This bilayer is composed of two layers of phospholipids, with hydrophilic heads facing outward and hydrophobic tails facing inward.

Consider the role of proteins: Proteins are interspersed within the phospholipid bilayer, serving various functions such as transport, signaling, and structural support.

Evaluate the dynamic nature: The fluid mosaic model emphasizes that the membrane is not static; components can move laterally, contributing to the membrane's flexibility and functionality.
