Function of peripheral proteins?
Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. Peripheral proteins are not bonded as strongly to the membrane. They may just sit on the surface of the membrane, anchored with a few hydrogen (H) bonds.
Why is protein synthesis important for cells and viruses?
Protein synthesis is important for viruses because the virus forces the host cell to make proteins that the cell does not need, but the virus does to repoduce. Protein synthesis is important for cells because the proteins are essential for all cellular activites.
Cell membranes are made up of?
a lipid bilayer - contains protein molecules & carbohydrates often attach themselves to these proteins
What is a common type of protein consumed?
All the proteins in the food is consumed. Once it enters the body it has to be digested to amino acids and not the proteins in the food directly go and attach in human cells.
What is viral protein?
Some viruses have a capsid with proteins that act as "docking stations" so that they can attach to host cells. Others without capsids also have a different type of protein that does the same thing.
What must HIV surface protein do to enter a host cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
Which type of membrane protein attaches to specific hormones such as insulin?
The membrane proteins that attach to specific hormones such as insulin are called receptor proteins.

Proteins at the inner surface of the plasma membrane attach the membrane to the cells support structure making the cell rigid?
false

What is the function of the peripheral protein?
Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. These molecules attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure. Proteins with GPI anchors are an exception to this rule and can have purification properties similar to those of integral membrane proteins.
What parts of a virus allow it to attach to a cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.

Functions of integral membrane protein?
Integral proteins are found within the membrane and have hydrophobic regions embedded within the membrane and hydrophilic regions that project from both surfaces of the bilayer Many integral proteins are glycoproteins, which have an attached carbohydrate chain. As with glycolipids, the carbohydrate chain of sugars projects externally. There- fore it can be said that the plasma membrane is "sugar- coated." The plasma membrane is asymmetrical: the two halves are not identical. The carbohydrate chains of the glyco-lipids and proteins occur only on the outside surface and the cytoskeletal filaments attach to proteins only on the inside surface
