Question

Which diagram best represents the fluid-mosaic model of a cell membrane?

Answer 1

The fluid mosaic model is the best representation of the cell membrane structure. It describes the cell membrane as a fluid combination of phospholipids, cholesterol, proteins, and carbohydrates. This model explains the dynamic nature of the cell membrane.

Step-by-step explanation:

The fluid mosaic model is the best representation of the cell membrane structure. According to this model, the cell membrane consists of a fluid combination of phospholipids, cholesterol, proteins, and carbohydrates. The proteins are embedded in the phospholipid bilayer, some extending all the way through and some only partially across it. This model accounts for the fluidity and dynamic nature of the cell membrane.

Answer 2

The fluid mosaic model describes the structure of a cell membrane as a fluid combination of phospholipids, cholesterol, proteins, and carbohydrates. The best diagram representation should show a phospholipid bilayer with embedded proteins and outer extensions of cholesterol and carbohydrates.

Step-by-step explanation:

The fluid mosaic model of a cell membrane describes its structure as a combination of components including phospholipids, cholesterol, proteins, and carbohydrates. According to the model, these components give the membrane a fluid and mosaic-like character. The proteins in the membrane can be categorized as integral proteins that are embedded within the phospholipid bilayer, with some extending all the way through the bilayer and others partially across it. To represent this model, the best diagram would show phospholipids forming a bilayer with embedded proteins, cholesterol, and carbohydrates extending from the outer surface.
