- Which of the following statements related to intercellular junctions is false? Cadherins are important cell-cell adhesion proteins. A cadherin-mediated junction involves many cadherin molecules to achieve strong adhesion. The cytoplasmic domain of cadherins interacts with actin or intermediate filament cytoskeleton through adaptor proteins. Because tight junctions seal the membrane of adjacent epithelial cells, transmembrane proteins in the apical portion of the plasma membrane cannot move to the basal lateral domain or vice versa. Proteins can diffuse through an open gap junction.arrow_forwardIdentify how each of the following would pass through the plasma membrane: gases, large polar molecules, charged molecules (like ions), hydrophobic molecules, and small polar molecules.
