Can someone help me on this Match the cytoskeletal filaments

Match the cytoskeletal filaments with their structure, specific motor protein composition, and cellular function. A. Microtubules B. Intermediate Filaments C. Microfilaments ____ thick, twisted, fibrous filaments A hollow tubules two intertwined filaments B anchorage of nucleus and other organelles within the cell ____chromosome movement during cell division ____muscle contraction ____ actin ____tubulin ____ keratin

1. A

2. A

3. C

4. B

5. A

6. C

7. C

8. A

9. B

A. Microtubules-

Made up of alpha beta tubulin dimer

Hollow tubules

These are made up of thick, twisted, fibrous filaments

Move chromosome during cell division

B. Intermediate filaments-

Made up of keratin, lamins and others

Anchor nuleus and some other organelles within the cell

C. Microfilaments-

Made up actin

2 strands of actin, each is made up of 2 helical interwined filament.

Move cella via muscle contraction or cell crawling.
