Final answer:
The five classes of proteins found in the prokaryotic cell membrane are transport proteins, receptor proteins, enzymes, structural proteins, and adhesion proteins.
Step-by-step explanation:
The five classes of proteins found in the prokaryotic cell membrane are:
- Transport proteins: These proteins are responsible for transporting molecules and ions across the cell membrane. Examples include ion channels and transporters.
- Receptor proteins: These proteins help the cell communicate with its environment by recognizing and binding to specific molecules or signals.
- Enzymes: These proteins catalyze chemical reactions within the cell membrane.
- Structural proteins: These proteins provide support and structure to the cell membrane.
- Adhesion proteins: These proteins help cells stick together or attach to surfaces.
