Tight junctions prevent the movement of the extracellular matrix between cells.

A) True
B) False

Which one is it please :)

To determine whether the statement is true or false, we need to understand what tight junctions are and their function.

Tight junctions are specialized protein complexes that form a barrier between cells, sealing the space between them. They are found in many types of tissues, including epithelial and endothelial tissues. The primary function of tight junctions is to prevent the movement of molecules and ions between adjacent cells, effectively controlling the passage of substances across epithelial or endothelial layers.

In this case, the statement is stating that tight junctions prevent the movement of the extracellular matrix between cells. The extracellular matrix (ECM) is a complex mixture of proteins and other molecules that surrounds cells and provides support and structural integrity to tissues.

Based on the above definition, tight junctions do not prevent the movement of the extracellular matrix between cells. The role of tight junctions is mainly to regulate the passage of substances between cells, rather than restricting the movement of the extracellular matrix.

Therefore, the correct answer is B) False.
