Structure of Plasma Membrane (1)

Fluid mosaic model

Model used to explain the structure of plasma membrane

Basic unit of plasma membrane

Phospholipid molecules that are arranged bilayer

The structure of plasma membrane

Consists of phospholipid bilayer, cholesterol molecule, carrier protein, pore protein, glycolipid and glycoprotein

Glycoprotein

Consists of the combination of protein and polysaccharide

Glycolipid

Consists of the combination of lipids and polysaccharide

Cholesterol molecule

Makes the plasma membrane stronger and more stable

Permeable membrane

A membrane that allows all types of molecules to pass through it freely

Impermeable membrane

A membrane that does not allow any molecules to move across it

Carrier protein

Transport large molecules such as glucose, amino acids and vitamin C across plasma membrane

Channel protein

Transport small molecules such as water and ions
