Indicate whether each of the following statements is likely to be true or false. Integrins are transmembrane components of “adhesion belts”. Tight junctions seal the plasma membrane of adjacent epithelial cells together. This makes it possible for directional membrane transport across the epithelial sheet to occur. Gap junctions are important structures for coupling the electrical and metabolic activities of adjacent cells. Gap junctions are always open. Extracellular matrix plays an important role in tissue formation and regeneration.
