10 Questions
What are the integral membrane proteins called that extend out from each cell and bind tightly together?
Cell adhesion molecules
In multicellular organisms, cells are able to bind to each other; this cellular property that mediates the binding is called:
Cell adhesion
Where are tight junctions found in the body?
Endothelial cells and epithelial cell membranes
What is the collective term for the extracellular components that provide a structural framework for cell binding?
Extracellular matrix (ECM)
What type of cell junction serves as a tight seal between neighboring cells?
Tight junctions
Cell adhesion molecules extend out from each cell and bind loosely together.
False
The binding of cells to the extracellular matrix is termed cell-matrix adhesion.
True
Tight junctions are found in muscle cells and nerve cells.
False
The cytosolic domains of cell adhesion molecules attach to the cell membrane.
False
Tight junctions prevent leakage between two cells in the epithelial membrane.
True
Test your knowledge on the mechanisms and properties of intercellular adhesions and junctions in multicellular organisms. Explore how cell adhesion molecules and cytoskeleton interactions contribute to the binding and organization of cells in tissues.
