Extensin is a component of cell walls. This protein is a hydroxyproline-rich glycoprotein, meaning that it has a backbone derived from the amino acid proline and side chains composed of several types of sugars. List the organelles that are involved in extensin (or any other glycoprotein) production and transport and describe what aspect of protein production and/or transport occurs in each organelle.
