A type of intercellular connection in which the outermost lipid portions of the two cell membranes is fused is termed a(n)

B) gap junction.
C) intermediate junction.
D) desmosome.
E) none of the above

Question

Quizplus · Accepted Answer

The description given in the question matches that of a tight junction, where the membranes of adjacent cells are fused together through the interaction of transmembrane proteins and outer leaflet lipids, forming a seal that prevents molecules from passing between the cells. Gap junctions allow for direct communication between cells via the exchange of small molecules, while intermediate junctions and desmosomes provide structural support and are anchored to the cytoskeleton.
