Currently writing a synoptic essay on the "Significance of Biological Membranes" and got a little stuck on something.

In the Fluid Mosaic Model, there are "Intrinsic" and "Extrinsic" proteins and I'm a little confused with these.

I know extrinsic appear on the outside(?) and intrinsic are embedded in the phospholipid bilayer but I'm struggling to find examples of these...If that makes sense?

Well an example of an intrinsic would be for the absorbtion of ions in the small intestine by the epithelial cells since the ions would disturb the bilayer so need the full protein to enter a cell.
