Proteins can be attached to a membrane in a variety of ways

Proteins can be attached to a membrane in a variety of ways. How does the mode of attachment relate to their function?

Solution

Membrane proteins are very important for different type of cellular functions like a transport signalling pathways and cell adhesion etc…. proteins are interacting with membrane in different types

Some proteins are associated with cytoplasmic face of the cell membrane; some proteins are associated with extracellular face of the plasma membrane (peripheral proteins) and integral or intrinsic proteins. Extrinsic proteins do not interact with the hydrophobic core of the phospholipids bilayer.

Example porins are transmembrane proteins that play a major role in water transport

Prostaglandin H₂ extracellular membrane bounded protein that is associated with surface of the plasma membrane. Play major role in inflammation.
