Pellicle
The pellicle of a paramecium is located underneath the plasma membrane, providing structural support and shape to the cell. It is composed of a network of protein strips called microtubules that run parallel to the cell surface.
Paramecium has a rigid outer covering called a pellicle that gives it its shape, while euglena's shape is maintained by a proteinaceous structure called the pellicle and supported by protein strips called microtubules underneath the cell membrane.
Inner membrane proteins are embedded in the inner membrane of bacteria, while outer membrane proteins are located in the outer membrane. To obtain membrane proteins from E. coli, you can disrupt the cells through methods like sonication or French press, followed by using differential centrifugation to separate the inner and outer membrane fractions based on their densities. Further purification techniques such as density gradient ultracentrifugation or membrane solubilization can be used to isolate inner and outer membrane proteins specifically.
elastic protein (maison.e)
The protein that projects from the outer surface of the membrane is termed as an extrinsic or peripheral membrane protein. These proteins are not embedded within the lipid bilayer but instead are attached to the surface of the membrane.

Lipo-protein membrane
elastic protein (maison.e)
A membrane protein with a carbohydrate chain is called glycoprotein
high variation of protein composition in membrane?

a membrane with no proteins -_-
Cell membrane pores are made up of protein.
Protein, because thats what the cell membrane does (delivers protein to the cell)
In order to be an integral membrane protein, a protein must have hydrophobic regions that can interact with the hydrophobic lipid bilayer of the cell membrane. These proteins are embedded within the membrane rather than just associated with the membrane surface.
