Membrane proteins are either extrinsic or intrinsic.

Extrinsic membrane proteins are entirely outside of the membrane, but are bound to it by weak molecular attractions (ionic, hydrogen, and/or Van der Waals bonds). Intrinsic membrane proteins, the class we are mainly interested in, are embedded in the membrane. Many of them extend from one side of the membrane to the other and are referred to as transmembrane proteins.

Cells are constantly pumping ions in and out through their plasma membranes. In fact, more than half the energy that are bodies consume is used by cells to drive the protein pumps in the brain that do nothing else but transport ions across plasma membranes of nerve cells.

Cells contain proteins that are embedded in the lipid bilayer of their plasma membranes and extend from one side of the membrane through to the other. Such transmembrane proteins can function to effect ion transport in several ways.

Hence Extrinsic protein is A membrane protein that partially span the membrane, and is attached either to the outer or to the inner phospholipid layer. Supplement.Extrinsic proteins serve in transport of molecules and as receptors. They are held to the cell membrane by weak molecular attractions, like ionic, hydrogen, or Van der Waals bonds.

hey here is your answer

EXTRINSIC PROTEIN

1)THEY HELP IN TRANSPORTATION

2)THEY ALSO CALLED AS RECEPTORS

3)THEY ARE WEAKLY CONNECTED WITH CELL MEMBRANE OF FORCES LIKE IONIC , HYDROGEN AND VANDER WALLS FORCES

HOPE IT HELPS YOU
