Target cell
The cell membrane contains the membrane proteins that enable a hormone to selectively bind to its plasma membrane. These proteins, such as receptor proteins, are responsible for recognizing and binding to specific hormones, allowing the hormone to exert its effects on the cell.
The proteinshave certain 'identifiers' attached to them, which only allow certain particles through, making it selectively permeable.
globular proteins .
The cell membrane is a phospholipid bilayer and contains proteins.
The primary filter to exclude proteins from the filtrate is the glomerular basement membrane in the kidney. This membrane selectively allows small solutes and water to pass through while preventing large proteins from being filtered out of the blood.

Integral membrane proteins, such as ion channels and transporters, span the plasma membrane and play a crucial role in creating a selectively permeable barrier. These proteins regulate the passage of specific ions and molecules across the membrane, allowing for the maintenance of cellular homeostasis.
Plasma membrane filters what the cell needs and keeps out what will harm it. this property is called selective permeability.

Channel proteins are on the plasma membrane, selectively transport the solutes such as ions, small and large proteins across the membrane. Carrier proteins also membrane proteins that allow diffusion of different molecules. Both proteins are chemically made up of amino acids.

The plasma membrane is a phospholipid bilayer membrane that surrounds the cell, serving as a protective barrier. It is selectively permeable, allowing certain molecules to enter and exit the cell. The plasma membrane also contains proteins that help with cell communication and transport.

In facilitated diffusion, proteins act as specific channels or carriers that assist in the movement of molecules across the cell membrane without the expenditure of energy. These proteins selectively bind to the target molecules, undergoing conformational changes that allow the substances to pass through the membrane more easily. This process is driven by the concentration gradient, enabling molecules to move from areas of higher concentration to lower concentration.
