Are there any diseases linked to actin filaments? Are any mutations that could halt the growth of actin filaments? I've learned about different drugs that affect filaments like Phalloidin, Cytochalasin, and Latrunculin. But other than drugs, what external environmental factors could halt the process of actin filaments from growing, and is there any diseases or illness that are associated with abnormal actin filament activity? Thank you.
Actin filaments in microvilli require the help of myosin so that they can associate with the microvilli cellular membrane. What type of myosin is utilized for membrane association? Myosin VII Myosin II O Myosin I O Myosin VI
Select the correct description explaining the assembly of intermediate filaments. O The process requires ATP binding to an intermediate filament protein - two dimers make a tetramer, then association of 8 tetramers form a filament. The process requires GTP binding to an intermediate filament protein-two dimers make a tetramer, then association of 8 tetramers form a filament. O No ATP/GTP binding to an intermediate filament protein required - two dimers make a tetramer, then association of 8 tetramers form a filament. Formation of a triple-helix, as seen in collagen, would be required for the assembly of intermediate filaments.
How does ADP facilitate kinesin "walking"?
Which of the following describes an F-actin microfilament? A flexible, helical filament composed of two strands assembled from G-actin 13 protofilaments composed of heterodimers with a hollow core a flexible filament composed of 13 interwoven protofilaments Eight tetramers twisted into a rope-like filament
If you were to watch muscle tissue contract: Under a light microscope, would you see the muscle fibers get narrower, or the striations get thinner? Explain. At the EM level, focusing on one sarcomere, you would be able to see a region of thick filaments overlapping two regions of thin filaments. Use the structure of the thick filaments to explain how ONE region of thick filaments is able to pull in microfilament in two opposite directions (both toward the center of the sarcomere).
Within a sarcomere, which of the following is a structural protein is used to attach the Z-disk to the M-line? O Actin O Myosin ñed) O Titin Thin filament Dystrophin
There are no known motor proteins that move along intermediate filaments, in contrast to the variety of such proteins that associate with microtubules and actin filaments. What characteristic of intermediate filaments, in their polymerized form, might explain the absence of associated motor proteins? Briefly explain your reasoning.
ATP within actin subunits is hydrolyzed after assembly into a filament but before disassembly from a filament. in theprocess of assembly into a filament. in the process of disassociation from a filament after disassociation from a filament
Which of the following does NOT limit normal clot growth to the sight of injury? O A) Removal and dilution of clotting factors O B) Fibrin binding to thrombin O C) Antithrombin III D) Exposed collagen fibers O E) Serotonin
Can you match the sacromere anatomy with the proper answer from the list below the table graph? Sarcomere Anatomy Description/Reaction Thin Filaments ? Thick Filaments ? A Band ? I Band ? M Line ? H Zone ? Z Disc ? A) G-Actin, F-Actin, Troponin, Tropomyosin B) Myosin C) Bisected by the M Line, this area shows only the thick filaments without any thin filamentous overlap D) The point of origin for myosin filaments found in the center of the sarcomere E) An area in the center of the sarcomere marked by the entire length of the thick filaments F) A space between sarcomeres with the z-disc in the center; this region shows Actin's anchorage points and extension without myosin overlap G) Anchoring point for the thin filaments
Which of the following proteins connects the actin filaments to the Z-band in the sarcomere? CapZ Titin Profilin Nebulin O Tropomodulin < Previous
