**Question:**Thick filaments ______________, but thin filaments do/are not.- are part of the I band- contain actin- contain myosin- are directly attached to the Z disk**Explanation:**This question requires you to choose the correct statement about the characteristics of thick filaments in muscle tissue, contrasting them with thin filaments. Understanding components like the I band, actin, myosin, and the Z disk is essential for answering this question accurately.

In each microfibril, actin thin filaments and myosin thick filaments are organized into a linear…

Answered: Thick filaments are part of the I band…

What is a sarcomere? Illustrate how Z disks, actinmyofilaments, myosin filaments, the M line, and titin form asarcomere. Describe how this arrangement produces theA band, the I band, and the H zone. Label these areas onyour illustration.
The sarcoplasmic reticulum releases ____________________ into the sarcoplasm. When Ca++ binds to troponin it exposes the _______________________ on the thin filament. In order for a cross bridge to form ______________________ must bind to the myosin head.
In the structure of a sarcomere, which of the following overlap with the region of the A-band? actin myosin 1-disks • two of the above all of the above
The T tubule is a protein complex that is part of the force generating structure that also includes actin, myosin, troponin, and tropomyosin True O False
Why is it that intermediate filaments have iden-tical ends and lack polarity, whereas actin filaments andmicrotubules have two distinct ends with a defined polar-ity?

Actin exits in two forms, a globular G form ( the free subunit) and a filamentous Fform( assembled into a filament. true false
What triggers the movement of the thin filament? Is it because of the high --> low energy configuration? The exact mechanism is confusing to me.
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.
What would be the consequence for actin filament assembly/disassembly if a mutation prevented actin’s ability to bind ATP? What would be the consequence if a mutation prevented actin’s ability to hydrolyze ATP?
