A decrease in cell adhesion, by the introduction of an experimental substance to a tissue, compromises the structural integrity of the tissue. Which cell junction would MOST likely be affected by this treatment causing a decrease in the strength of the tissue?
A)adherens junctions
B)gap junctions
C)hemidesmosomes
D)tight junctions

Question

Quizplus · Accepted Answer

Adherens junctions provide mechanical support to tissues by linking actin filaments of neighboring cells together. A decrease in cell adhesion would likely affect these junctions, compromising the strength of the tissue. Gap junctions provide channels for communication between cells, hemidesmosomes anchor epithelial cells to the underlying basement membrane, and tight junctions seal the extracellular space between cells to prevent leakage of substances. While these junctions are important for different functions, they are less directly involved in providing structural support to tissues.
