Cell
The Golgi body
Membrane proteins and all other proteins are produced in cytoplasm. The proteins targeted to membranes by specific signals. Golgi vesicles transport the proteins to membrane. Not all proteins are membrane proteins
Surprisingly, membrane proteins are found in or attached to the membrane.
Receptor proteins are typically membrane proteins, meaning they are located on the cell membrane.
Integral membrane proteins: embedded within the lipid bilayer. Peripheral membrane proteins: bound to the membrane surface. Receptor proteins: involved in cell signaling and communication. Channel proteins: facilitate the passage of ions and molecules across the membrane.
After integral membrane proteins are synthesized in the rough endoplasmic reticulum (ER), they are transported to the Golgi apparatus. The Golgi apparatus modifies, sorts, and packages these proteins for their final destinations, which can include various membranes within the cell or secretion outside the cell. The proteins are then transported in vesicles that bud off from the Golgi.

Membrane proteins.
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.
These are proteins. Transmembrane proteins span the entire membrane.
