What does ER help in synthesis of protein?
Endoplasmic reticulum (ER) plays a crucial role in the synthesis of proteins by providing a site for ribosomes to attach and synthesize proteins. The rough ER, with ribosomes attached to its surface, is involved in the synthesis of proteins that are destined for secretion or insertion into membranes. The smooth ER is involved in the synthesis of lipids and detoxification processes rather than protein synthesis.
Cell membranes are made up of?
a lipid bilayer - contains protein molecules & carbohydrates often attach themselves to these proteins
Enzymes that attach carbohydrates and lipids to proteins are called?
Enzymes that attach carbohydrates to proteins are called glycosyltransferases, while enzymes that attach lipids to proteins are called acyltransferases. These modifications play important roles in protein structure and function.
What property of a virus determines its attachment to a host cell membrane?
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.
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 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.
To which specific part of the pathogen do antibodies attach?
Antibodies attach to specific proteins on the surface of pathogens, called antigens, to help neutralize and eliminate them from the body.

What is the function of ubiquitins?
Ubiquitins are small proteins that regulate protein degradation by marking target proteins for destruction by the proteasome. They attach to proteins targeted for degradation and signal for their removal from the cell. This process helps maintain cellular homeostasis by controlling protein levels.
Proteins at the inner surface of the plasma membrane attach the membrane to the cells support structure making the cell rigid?
false
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.
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.
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.
