At structures called ________, two cells are held together by membrane proteins that function as a narrow passageway, allowing ions, small metabolites, and regulatory molecules to pass from cell to cell.
A) anchoring junctions
B) CAMs
C) focal adhesions
D) zonula adherens
E) cell junctions

Question

Quizplus · Accepted Answer

The structures described are cell junctions, specifically gap junctions. They allow for communication and exchange of small molecules between cells. Anchoring junctions, CAMs, focal adhesions, and zonula adherens are all different types of cell-to-cell or cell-to-matrix junctions that serve different functions.
