In the phospholipid bilayer
Carrier proteins are typically found embedded in the cell membrane, where they facilitate the passage of specific molecules across the membrane through binding and conformational changes. Channel proteins are also found in the cell membrane and form pores that allow for the passive movement of molecules down their concentration gradient.
Receptor proteins are typically membrane proteins, meaning they are located on the cell membrane.
Ribosomes are responsible for assembling proteins in the cell by reading mRNA transcripts and facilitating the process of translation to produce the protein structures. Ribosomes are composed of proteins and RNA molecules and can be found in the cytoplasm or on the endoplasmic reticulum in eukaryotic cells.
Ribosomes produce the proteins needed in a cell
Transport proteins are typically located in cell membranes, where they facilitate the movement of molecules across the membrane. These proteins can be found in both the plasma membrane of the cell and the membranes of intracellular organelles such as the mitochondria and endoplasmic reticulum.
In the cell membrane.
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.

The cell membrane is a phospholipid bilayer and contains proteins.

Every cell has proteins. All genes ultimately code for proteins. Proteins are involved in virtually all (if not all) cell processes. Proteins are found in the cell membranes, in the cytosol, in organelles, in the bloodstream, basically everywhere.
Proteins not found in the cell membrane include histones (associated with DNA in the nucleus), cytoskeletal proteins (maintain cell shape and structure), and enzymes located in the cytoplasm or organelles.
Other proteins support cell functions and are found embedded in membranes. Proteins even make up most of your hair. When a cell needs to make proteins, it looks for ribosomes.
Receptor proteins are typically membrane proteins, meaning they are located on the cell membrane.
