What are the three components of a cell membrane?

Answer 1

Lipids, proteins, and carbohydrates. Proteins are integral and transmembrane. The transmembrane protein span the entire membrane outside to inside and often act as transport proteins. The integral proteins do not span both ends of the membrane. The lipids (obviously) make up the lipid bilayer. The carbohydrates are short chains that attach to the other two organic molecules, when they attach to a protein they are known as 'glycoproteins' and when they are attached to lipids they are called 'glycolipids'. These carbohydrates play a key role in cell to cell recognition.

In other words, Lipids, Proteins, and Carbohydrates make up the cell..

Answer 2

Here are the major organic compounds:

A cell membrane contains phospholipids, lipids (e.g. cholesterol), and proteins.

The cell walls of plants contain the polysaccharide cellulose (a polymer of glucose).

Cell walls of fungi contain the polysaccharide chitin (which contains nitrogen, being a polymer of N-acetyl glucosamine).

Cell walls of bacteria contain peptidoglycan.

Answer 3

The cell membrane consists of a phospholipid bilayer. i.e. 2 layers of phospholipid molecules. Interspersed among the phospholipids are proteins which are used in the processes of facilitated diffusion of materials in and out of the cell. Some molecules called glycoproteins also exist within the membrane wherein carbohydrates are attached to proteins.

thats phospholipids, proteins, and glycoproteins

Answer 4

1. Lipid Bilayers -Its function is to give the cell membrane a tough flexible structure that protects the cell from its surroundings.

2. Protein- Its function is to run though the lipid bilayers.

3. Carbohydrates - Its function is to form chains that are attached to outer surfaces of the proteins.
