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.

Proteins made and modified here for secretion from cell?
Golgi Apparatus
What has a secretion that contains cell fragments?
Sebaceous glands secretion contains cell fragments. Sweat gland apocrine produce a secretion containing proteins and fats in addition to water and salts.
Secretion of cell products like milk proteins and mucus from glandular cells?
Microfilaments
Proteins destined for export from the cell are synthesized with a signal sequence and begin their synthesis?
golgi complex
What serves as receptors or cell recognition molecules on cell surfaces?
Glycolipids are membrane carbohydrates covalently bonded to lipids. According to Campbell Reece's book AP Edition Biology 7th Edition, these are the most important molecules in cell to cell recognition.
What do glycoproteins have that simple proteins do not?
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.
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 directs newly synthesized protein to its target?
Protein targeting in the cell is carried out via endoplasmic reticulum (ER) and mainly exported by Golgi apparatus (through vesicles). Proteins that have signal sequences will be destined to the nucleus and other organelles. Secretion of proteins to the cell membrane and out of cell by secretory vesicles.
What are the four types of protein in a cell membrane?
transport proteins receptor proteins enzyme proteins cholesterol
Where are proteins made and modified for secretion from cell?
Golgi apparatus
What is the major component of the cell membrane?
Phospholipids are the major component of cell membranes, but there are proteins, glycoproteins and cholesterol also in the membrane.

What cell package materials from the . and send them to other parts of cell?
Golgi bodies involve in packaging.It converts proteins and lipids into glycoproteins and glycolipids and transports.
What the function of Golgi apparatus?
Changing proteins and lipids into glycoproteins and glycolipids Packing synthesized materials in secretory vesicles and transporting Producing lysosomes Producing polysaccharides needed for synthesis of cell wall exept cellulose
What materials are found in the plasma membrane?
Phospholipid bilayer, embedded proteins, sugars forming the cell coat.
