A) Gap junction
B) Tight junction
C) Desmosome
D) Connexin
E) Integrin

Question

Quizplus · Accepted Answer

Gap junctions are specialized cell junctions that allow for the rapid spread of electric current via the flow of ions between animal cells. They are formed by connexin proteins and are commonly found in tissues that require fast electrical communication, such as cardiac and smooth muscle. Tight junctions and desmosomes are types of cell junctions that are involved in cell adhesion and tissue integrity, but do not allow for the flow of ions between cells. Integrins are transmembrane proteins that serve as receptors for extracellular molecules and are involved in cell signaling and adhesion.
