Intermediate Filaments Help Protect Animal Cells from Mechanical Stress Because

question 17

Multiple Choice

Intermediate filaments help protect animal cells from mechanical stress because filaments

• A)directly extend from the interior of the cell to the extracellular space and into the next cell, linking one cell to the next, helping to distribute locally applied forces.
• B)in each cell are indirectly connected to the filaments of a neighboring cell through the desmosome, creating a continuous mechanical link between cells.
• C)remain independent of other cytoskeletal elements and keep the mechanical stress away from other cellular components.
• D)make up the desmosome junctions that connect cells; these junctions are more important than the internal network of filaments for protecting cells against mechanical stress.
