Within the cell membrane. what is the role of proteins?

Best Answers

The collection of proteins within a cell determines its health and function. Proteins are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance. read more

Peripheral proteins can be found on either side of the lipid bilayer: inside the cell or outside the cell. Membrane proteins can function as enzymes to speed up chemical reactions, act as receptors for specific molecules, or transport materials across the cell membrane. read more

The functions of a membrane protein include cell cohesion, relaying signals between the inside and outside of a cell and transporting proteins across the membrane. A membrane protein is a protein that is attached to a cell and interacts with biological membranes. read more

While the lipid bilayer provides the structure for the cell membrane, membrane proteins allow for many of the interactions that occur between cells. As we discussed in the previous section, membrane proteins are free to move within the lipid bilayer as a result of its fluidity. read more

The cell membrane has one MAJOR function: regulate the movement of water and other ion in/out of cells. It consist mainly of lipids (bilipid layer). Within the bilipid layer are transport proteins regulate the influx/efflux of ions, e.g. charged molecules like H2O, Na, K, Ca, glucose and so on. read more
