Question

We have considered several different kinds of cell-cell junctions found in epithelial cells. For the two types here, tight and adherens junctions, select the correct properties or functions associated with it: (A) Major source of adhesion between cells (B) Brings the plasma membrane of adjacent cells into such close apposition that even small molecules can't leak between the cells. (C) Allows epithelia to maintain solute gradients between their apical and basal sides. (D) Signaling: recruits signaling molecules to its cytoplasmic side that convey information to the cell about its surroundings. (E) Keeps the sheet anchored: mediates interaction of the cells with the basal lamina, or underlying extracellular matrix. (F) Interacts with actin filaments on their cytoplasmic sides (G) Shape and mechanical strength: contributor to the resistance of the whole epithelial sheet to stretching and tearing, and/or to its ability to change shape. (H) contains transmembrane proteins of the integrin family (I) Interacts with intermediate filaments at their cytoplasmic sides (J) contains transmembrane proteins of the cadherin family

Explanation / Answer

Ans).Tightjunctions: Brings the plasmamembrane of adjacent cellsinto such close apposition that even small molecules can't leak between the cells.

Adherens junction: Shape and mechanical strength: contributor to the resistance of the wholeepithelial sheet to stretching and tearinand or its ability to change shape.
