Cell Membrane Structure

Question 1

Proteins with carbohydrate chains extending outwards for cell recognition and signalling, found on the extracellular surface

Answer 1

Glycoprotein

Question 2

Lipids with carbohydrate chains facing the extracellular enviroment, aiding in stability and communication

Answer 2

Glycolipid

Question 3

A molecule located within the cell membrane structure between phospholipids in the bilayer mainly found in animal cell membranes, regulating fluidity

Answer 3

Cholestrol

Question 4

A type of transmembrane protein that forms hydrophilic pores that allow specific molecules or ions to pass through the bilayer

Answer 4

Protein Channel

Question 5

Proteins attached to either the inner or outer surface, interacting with phospholipid heads or integral proteins for support and signalling.

Answer 5

Peripheral Protein

Question 6

Proteins that are embedded within the bilayer, often spanning across it (transmembrane), functioning in transport and signalling

Answer 6

Integral Protein

Question 7

A double later of phospholipids forming the fundemental structure of the cell membrane, with the hydrophobic heads facing outwards (intracellularly and extracellularly)

Answer 7

Phospholipid Bilayer

Question 8

The nonpolar fatty acid chains of phospholipids that repel water and face inward, forming the membrane’s interior.

Answer 8

Hydrophobic Tail

Question 9

The polar phosphate-containing part of phospholipids that attracts water and faces outward toward the aqueous environment.

Answer 9

Hydrophilic Head
