Chapter 7.5, Problem 3CC
Summary Introduction
To explain: Cellular synthesis and deposition of extracellular matrix (ECM) glycoprotein.
Concept introduction: Animal cells do not have cell wall but consists of plasma membrane. The cell synthesizes and secretes material outside of cell called extracellular matrix (ECM). The secretion of material outside the cell is carried out by a process called exocytosis. The ingredient of ECM includes glycoprotein and other carbohydrate containing molecules. Collagen is the most important and abundant glycoprotein in the ECM. Another protein called fibronectin is also present in the ECM. ECM plays a role in the cellular functions and protection. It provides signal to the animal cell that allows communication with the extracellular environment.

- Part C - Facilitated diffusion via channels and carrier proteins The majority of solutes that diffuse across the plasma membrane cannot move directly through the lipid bilayer. The passive movement of such solutes (down their concentration gradients without the input of cellular energy) requires the presence of specific transport proteins, either channels or carrier proteins. Diffusion through a transport protein in the plasma membrane is called facilitated diffusion. outside cell channel protein inside cell carrier protein' Adapted from Biology by Campbell and Reece ©2008 Pearson Education, Inc.

The cellular membrane is critical to the maintenance of homeostasis in living organisms. The cell membrane separates the cell from the external environment and plays a critical role in regulating movement of material in and out of the cell. Additionally, eukaryotic cells are made complex by the presence of internal membranes that form organelles, so the cells may become specialized. These organelle membranes create compartments within the cell that can do specific functions. For this exercise, you will work in groups of four to progress through the activities. At the end of each activity, one group (chosen at random) will share how they responded and open the floor for further discussion.

From the rER, proteins are transported to the Golgi where the protein is further modified As it enters the cisternal space inside the ER, it falds up into its correct 3-dimensional shape. Ribosomes on the surface of the endoplasmic reticulum (ER) translate MANA into a polypeptide chain. Most proteins destined for secretion are glycoproteins (.e. they are proteins with carbohydrates added to them). Attachment of Ribosome carbohydrate to the protein by enzymes (glycosylation) occurs in the rER.
