-
Match each of the following to its role in the cell.
- A. B. C. D. E. F. G. H. Microtubules
- A. B. C. D. E. F. G. H. Actin
- A. B. C. D. E. F. G. H. Tubulin
- A. B. C. D. E. F. G. H. Intermediate filaments
- A. B. C. D. E. F. G. H. Kinesin
- A. B. C. D. E. F. G. H. Dynein
- A. B. C. D. E. F. G. H. Myosin
- A. B. C. D. E. F. G. H. Centrosome
A. Motor protein responsible for anterograde transport of vesicles from Golgi complex to the plasma membrane.
B. Motor protein whose activity results in contraction of muscle.
C. Thinnest cytoskeletal filament. Responsible for initiation of amoeboid cell movement via pseudopod formation.
D. Cytoskeletal structure with the largest diameter. Serves as the "train tracks" for transport of vesicles and organelles to and from the cell membrane.
E. Cytoskeletal fiber that is intermediate in diameter and very sturdy. Does not form from
polymerization of protein monomers like the other ones we discussed in class, but consists of polypeptide strands. Keratin and Lamin A are examples.F. Motor protein responsible for retrograde transport of endosomes from the plasma membrane to the interior of cells.
G. The structure that initiates polymerization of new microtubules and anchors microtubules in the center of the cell near the Golgi Complex.
H. The "monomer" unit of the thickest cytoskeletal
polymer ; a dimer of two polypeptide subunits.
