There are several functions, but two main types are integral and peripheral proteins. Integral proteins act as channels, while peripheral proteins can do a variety of tasks, such as act as second messengers or receptors.
The proteins of the plasma serve the function of acting as porins. Porins are channels control the transport of substances in and out of the cell, imparting the membrane its property of semipermeabililty. Also, proteins make up 60-70% of the plasma membrane and thus form the bulk of it. Besides, the proteins are also involved in some important cellular reations.
Proteins are present in cellular membranes for a host of reasons. Not only do they provide form and shape to a cell, but they are also responsible for inner organization, product manufacture, waste cleanup, and routine maintenance. Proteins also receive signals from outside the cell and mobilize intracellular responses.
Many are active and passive transmember proteins for the passage of material into and out of the cell and some are markers on the cell surface that distinguish one bodies cells from another bodies cells.
they act as carrier protiens, assisting in selective permeability of the plasma membrane.
It sends signals between the cells external and internal environment.
Of course not,it is not a function of cell membrane.It is the function of ribosomes.
a very thin membrane, composed of lipids and protein, that surrounds the cytoplasm of a cell and controls the passage of substances into and out of the cell
protein channels
Membrane Protein
It has ribosomes on its membrane and provides surface area for protein synthesis.
They help move material in and out of the cell.
Of course not,it is not a function of cell membrane.It is the function of ribosomes.
Proteins are not primary components of cell membrane. The proteins on the cell membrane have special functions, like receptors and transporters.

The true question is, what is the function of an Endoplasmic Reticulum? The answer is were the cell membrane is assembled and some protein.
Protein, because thats what the cell membrane does (delivers protein to the cell)
No, the site of protein synthesis is the ribosomes, free and bound. The ribosome is the " workbench " on which proteins are made. Proteins can be imbedded in the membrane and can span the membrane.
yes, cell membranes are semipermeable.
What part of the membrane helps chemical reac
A thin membrane enclosing a striated muscle fiber. Its the function of 'a cover' of a cell.
The function of the cell membrane is to control what enters and leaves the cell.
