If two cells are attached with tight junctions, this means:
Fluid cannot pass freely in-between them
They have a very strong connection with each other
lons can pass directly from one cell to the other
One cell is epithelial and one cell is connective

Question

Accepted Answer

∻Answer∻ ⚹ Fluid cannot pass freely in-between them ⚹ ∻Solution∻ ‖ a ⋮ Tight junctions are specialized connections between adjacent cells that create a barrier to prevent the passage of molecules and ions through the space between cells. ‖ ‖ b ⋮ These junctions are typically found in epithelial tissues, where they help maintain the distinct environments on either side of the epithelial layer. ‖ ‖ c ⋮ Tight junctions are composed of transmembrane proteins such as claudins and occludins, which interact to form a seal. ‖ ∻Key Concept∻ ⚹ Tight junctions create a barrier to fluid and ion passage between cells. ⚹ ∻Explanation∻ ⚹ Tight junctions are crucial for maintaining the integrity of tissues by preventing the free passage of substances between cells, thus ensuring that the internal environment of the tissue is controlled and distinct from the external environment. ⚹◊What is the function of tight junctions in cell communication in epithelial tissues?⍭ Generate me a similar question◊
