Anna Huryn Week #3: BIO 183 Dr. Miriam Ferzli The Endomembrane System Cell Surfaces: The Cell Wall  Found in plants, prokaryotes, fungi and some protists  Serves multiple functions, in plants it protects the cell, maintains its shape, prevents excessive uptake of water, and supports the plant against the force of gravity  Animal cells lack a cell wall but instead have an elaborate extracellular matrix The Extracellular Matrix (ECM)  Made up of glycoproteins the most abundant being collagen which forms strong fibers outside of the cell  Embedded in a network of proteoglycans  Fibronectin attaches the ECM to integrins Integrins = receptor proteins in the plasma membrane which transmit stimuli between the cell’s external and internal environment Anna Huryn Week #3: BIO 183 Dr. Miriam Ferzli Surface Proteins & Cell Identity:  Cells of the same type recognize each other o Identity is determined by surface markers (on ECM) Ex. glycolipids on the surface of red blood cells determine the A, B, O blood groups  Immune system of vertebrates uses specific surface markers to distinguish “self” from “non-self” Intercellular Junctions:  Plant cells have plasmodesmata which allow cytosol to pass between cells  Animal cells have tight junctions, anchoring junctions, and gap junctions Local signaling = direct cell-to-cell contact Long-distant signaling = uses hormones to communicate with cells not next to each other Three Stages of Signaling: 1. Receptor Activation = a chemical signal binds to a cellular protein at the cell’s surface or inside the cell.  The signal molecule is a ligand, a small molecule that binds with specificity to a larger molecule (the receptor). 2. Signal Transduction = binding leads to a change in the receptor that triggers a series of changes in a series of different molecules 3. Cellular Response = the transduced signal triggers a specific cellular activity
