Glycoproteins have a carbohydrate, glycogen, attached to them. They face the outside of a cell, and are vital for certain functions, such as cell to cell recognition.

The ER sends proteins and lipids it makes to what to be modified?
The endoplasmic reticulum (ER) sends proteins and lipids in membranous vesicles to the Golgi body (also known as the Golgi apparatus or the Golgi complex). The Golgi body looks like a stack of pita breads; it resembles the ER. There, the membranous vesicles containing proteins or lipids will fuse with one side of the Golgi body known as the cis face.Inside the Golgi body, proteins and lipids will have carbohydrate molecules added to them, forming glycoproteins (proteins with carbohydrates attached) and glycolipids (lipids with carbohydrates attached). After being modified, the glycoproteins and glycolipids will exit the Golgi body in membranous vesicles through the trans face (the side opposite the cisface).
What do glycoproteins attached to?
oligosaccharides
Plasma membranes are a feature of?
Like all other cellular membranes, the plasma membrane consists of both lipids and proteins
Physiological function of oligosaccharite?
Oligosaccharides are sugars fewer than 15 sugar units and can be found on the external surface of a cell surface membrane. They are usually covalently bonded to lipids or proteins, forming glycolipids or glycoproteins. They serve as recognition sites for cell to cell recognition and adhesion.
What is the key structural element of a cell membrane?
The primary structural component of a cell membrane is the phospholid layers. This is mainly made of proteins which facilitate various cell activities.
Proteins with sugar molecules attached to them are called what?
glycoproteins
What is the function of the glycoproteins on the outside of the virus?
Glycoproteins are proteins that contain sugars and polipetides.
Why are most proteins destined for secretion from the cell glycoproteins?
because most proteins destined for secretion are glycoproteins (i.e. they are proteins with carbohydrates added to them); the carbohydrate is attached to the protein by enzymes.
What are the glycoproteins made up of?
Carbohydrates + proteins
What is in a lipid bilayer?
Many proteins,glycoproteins,glycolipids
What proteins enable cells to sense their surroundings?
Glycoproteins
What are membrane proteins that bind to signals by which cells communicate?
receptor proteins
Glycoproteins are membrane proteins?
Yes they are found as integral membrane proteins in addition to lipidis, glycerol and proteins alone. Glycoproteins are proteins that are post translationally coneected to sugar chains. Mostly the secreted proteins are also glycoslated.
What are the Function of glycoprotein?
Glycoproteins are proteins that are released in the blood. Glycoproteins have an important role in the immune system and cell recognition in mammals.
What are some of the glycoprotein's functions?
Glycoproteins are proteins that are released in the blood. Glycoproteins have an important role in the immune system and cell recognition in mammals.
What are proteins with suger molecules allached to them called?
Proteins with saccharides (sugar molecules) attached to them are known as glycoproteins.
Glycoproteins and proteoglycans are combinations of proteins and?
[protein molecules and] carbohydrate molecules.
