There are four primary types of protein subunits: globular, fibrous, membrane, and disordered. Each type serves different functions within the cell and has unique structural characteristics.
The plasma membrane of a cell consists of a phospholipid bilayer embedded with proteins. It acts as a barrier that controls the entry and exit of substances into and out of the cell. It also plays a role in cell signaling and communication with the environment.
All living cells contain a cell membrane, genetic material (DNA or RNA), ribosomes for protein synthesis, and cytoplasm where cellular activities take place.
Actually, bilipid "heads" form the layers of the membrane, but there are carrier proteins that transport objects into and out of the cells. These carrier proteins use either active or passive transport to get objects across the membrane. Active transport uses energy, while passive transport doesn't need to use energy to get items across. Hope this helps!!!

Structural support: Proteins in the cell membrane act as structural components, helping to maintain the shape and stability of the membrane. Transport: Some proteins in the cell membrane facilitate the movement of molecules and ions across the membrane, regulating the transport of substances in and out of the cell. Cell signaling: Proteins in the cell membrane can serve as receptors, transmitting signals from the external environment to the interior of the cell to initiate cellular responses. Cell adhesion: Proteins in the cell membrane can participate in cell-cell adhesion, allowing cells to bind to one another and form tissues or organs.
The four main cell components are the cell membrane, nucleus, cytoplasm, and organelles. The cell membrane acts as a barrier, the nucleus houses genetic material, the cytoplasm contains various organelles, and organelles carry out specific functions within the cell.
The four characteristics that eukaryotic and prokaryotic cells share are cell membrane, genetic material (DNA/RNA), ribosomes for protein synthesis, and cytoplasm where cellular activities occur.

Cell membrane: Surrounds the cell and controls the movement of substances in and out of the cell. Nuclear membrane: Surrounds the nucleus and regulates the passage of molecules between the nucleus and the cytoplasm. Mitochondrial membrane: Found in mitochondria and is involved in energy production through cellular respiration. Endoplasmic reticulum membrane: Forms a network of membranes within the cell and is involved in protein and lipid synthesis.
The cell membrane is the outer boundary of animal cells and plant cells, but plant cells also have a cell wall to protect their cells. The cell membrane and cell walls are the outer boundaries of cells.

Plasma membrane is the same as "cell membrane" it's one of the four characteristics of all cells. So plasma membrane is found "coating" the outside of all cells.
