Proteins embedded in the plasma membrane are called integral membrane proteins.

Here's why:

* Integral means they are firmly embedded within the membrane, often spanning the entire width.

* Membrane proteins indicates their location within the membrane.

There are other types of membrane proteins:

* Peripheral membrane proteins: These are associated with the membrane surface, but not embedded within it. They are attached through interactions with integral membrane proteins or membrane lipids.
