4. Name 7 specialized proteins that are embedded in the phospholipid bilayer. Describe the function of each of the 7 proteins.

7 specialized proteins that are embedded in the phosholipid bilayer are;

1) Intercellular joining

2) Carrier (Transport) proteins

3) Channel proteins

4) Receptor proteins

5) Anchoring proteins

6) Glycoprotein

7) Enzymatic protein

Explanation:

1) Intercellular joining - They enable cells to adhere (hold on) to each other and they also enable inter cellular communication

2) Carrier (Transport) proteins - Assist in the transport of ions, small and macro molecules such as glucose or other proteins  to cross a biological membrane

3) Channel proteins - Provides a hydrophilic passageway through cell membrane for water and polar ions

4) Receptor proteins -  Receptor proteins are the proteins on the surface or inside the target cells that receive signals sent to an intended target cell

5) Anchoring proteins - Assist cytoskeleton which holds up the organs used for anchoring within cells

6) Glycoprotein - Glycoproteins are proteins that have sugar attached to them and they function as providing chemical name-tag such as to define the matching organ in an organ transplant by corresponding glycoproteins

7) Enzymatic protein - Lower the activation energy of biochemical reactions.
