Function of the Carrier Protein

Involved in passive and active transport.

Carries ions or molecules across the plasma membrane.

It is a PARTIALLY PERMEABLE barrier.

The molecules are detached when a phosphate group is attached to the end of the protein.

1 of 5

Function of the Cholesterol

Fits between the phospholipids.

It gives the plasma membrane mechanical stability and flexibility.

2 of 5

Function of the Channel Protein

It is water-filled lined with hydrophilic amino acids.

It has compartments in it that are complementary to specific molecules (changes shape).

Spans across the entire lipid bilayer.

Water molecules and large molecules enter and leave through the channe

Function of a Glycoprotein

This is a carbohydrate chain.

Attached to the protein molecule.

This enables CELL SIGNALLING to occur so the cells can communicate to each other.

4 of 5

Function of a Glycolipid

This is also a carbohydrate chain.

Attached to the lipid molecule.

This also enables cell signalling so the cells can communicate to one another
