Practice question · True or false
Intermediate filaments are the most dynamic of the three cytoskeletal systems.
Hints
- Which system exists purely to resist mechanical stress?
- Intermediate filaments are the stable, rope-like ones; the other two assemble and disassemble constantly.
Show the answer
False
Why
False, intermediate filaments are the least dynamic. Microfilaments and microtubules turn over continuously, which is what lets them remodel; intermediate filaments are stable ropes whose whole purpose is to resist mechanical stress.
