They help control what enters and leaves the cells.
Proteins embedded in the cell membrane often act as receptors for signaling molecules or transporters for ions and molecules across the membrane. Carbohydrates attached to proteins and lipids in the cell membrane are involved in cell-cell recognition and communication, as well as providing structural support to the membrane.

The plasma membrane is composed of lipids (phospholipids, cholesterol), proteins, and carbohydrates. These components help maintain the structure and function of the membrane, allowing it to control the passage of substances in and out of the cell.

Receptor proteins are embedded in the lipid bilayer of the cell membrane.
A double phospholipid bilayer has embedded proteins, such as integral membrane proteins, that help facilitate various functions within the cell membrane. These proteins can serve as transporters, receptors, enzymes, or structural components, and play a crucial role in maintaining cell structure and function.
Proteins, specifically integral membrane proteins, are often embedded within the lipid bilayer to facilitate the movement of substances across the membrane. These proteins can function as channels or carriers, enabling selective transport of ions and molecules. Additionally, peripheral proteins may assist in signaling or structural roles but are not embedded like integral proteins. Together, they play a crucial role in regulating the permeability and functionality of the cell membrane.
Proteins, specifically membrane proteins, are often embedded within the lipid bilayer to facilitate the movement of substances across the membrane. These proteins can be classified as channel proteins, which provide passageways for specific ions and molecules, or carrier proteins, which bind to substances and undergo conformational changes to transport them across the membrane. Additionally, some of these proteins function as receptors, helping to signal and regulate the transport process.
Integral membrane proteins are embedded within the lipid bilayer of the cell membrane, while peripheral membrane proteins are only temporarily associated with the membrane. Integral membrane proteins have hydrophobic regions that interact with the lipid bilayer, while peripheral membrane proteins do not penetrate the lipid bilayer. In terms of function, integral membrane proteins are involved in transport, signaling, and cell adhesion, while peripheral membrane proteins often serve as enzymes or participate in cell signaling pathways.
The membrane receptors are proteins that are synthesized on ribosomes located in the cytoplasm of the cell. Once synthesized, these proteins are then transported to the cell membrane where they become embedded and function as receptors for specific signaling molecules.
