What is the function of protein in a cell membrane?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

they act as carrier protiens, assisting in selective permeability of the plasma membrane.

Answer 6

It sends signals between the cells external and internal environment.
