The major function of adhesion proteins such as fibronectin isto supportcommunication between adjacent cells. link collagen,proteoglycans, and cells containing integrins. seal celllayers at tight junctions linkepithelial cell layers. Cellulose, chitin, and hyaluronan are all depositedextracellularly by ABCtransporters. exocytosis. transmembraneenzyme complexes. secretion. Primary plant cell walls are cross-linked by lignin. pectin. turgin. hemicellulose. _______, although structurally different from gap junctions inanimal cell tissues, may be thought of as the functional equivalentof gap junctions in plants. Hemidesmosomes Plasmadesmata Adherensjunctions Desmosomes Proteins of the _______ family link transmembrane proteins ofthe tight junction to actin. zonulaoccludens plectin plakin catenin Animal cells are embedded in a(n) hemicellulose-rich hyaluronan layer. cellwall. pectin-richbasal lamina. extracellularmatrix. What is the difference between Gram-positive and Gram-negativebacteria? Gram-positivebacteria are surrounded by a single membrane, whereas Gram-negativebacteria are surrounded by a double membrane, with an outermembrane that is porous to ions and small molecules. Gram-positivebacteria are surrounded by a single membrane and Gram-negative bytwo membranes, with an inner membrane that is porous to smallmolecules and ions. Gram-positivebacteria are motile and Gram-negative are not. Gram-positivebacteria make gramicidin A and Gram-negative bacteria do not. The major transmembrane proteins in tight junctions include allof the following except claudin. thrombospondin. occludin. JAM(junctional adhesion molecule). Integrins link extracellular matrix proteins either directly orindirectly to all of the following intracellular proteinsexcept actin. -actinin. laminin. talin.
