Which cell junctions form a barrier to the passage of materials?
kkurt [141]

Answer:

The correct answer is - tight junctions.

Explanation:

Tight junctions are one of the cell-cell junctions that make a barrier to the passage of material which is a present in epithelia. This barrier is impermeable to most of the materials with soluble molecules. This barrier is made up of the occludin and claudin proteins.

Tight epithelia have tight junctions and examples of such junctions are the distal convoluted tubule or DCT, and the collecting duct of the nephron in the kidney.

Thus, the correct answer is - tight junctions.

En esta reacción, las células de levadura utilizan glucosa (azúcar) y oxígeno (del aire) para producir energía. También producen agua y dióxido de carbono (un gas). Este es el mismo proceso químico utilizado por los humanos.
