What is dynein?
Dynein is a motor protein that moves along microtubules within cells and is involved in various cellular processes, including the transport of organelles, vesicles, and other cargoes. It plays a crucial role in cell division, intracellular transport, and ciliary/flagellar movement.
What protein powers both the movement of cilia and vesicles within a cell?
Dynein is the protein that powers the movement of both cilia and vesicles within a cell. It is a motor protein that uses ATP hydrolysis to generate force and facilitate movement along microtubules.
Cilia and flagella move due to energy provided by the enzymatic breakdown of ATP by what?
The movement of cilia and flagella is powered by the ATP-dependent motor protein dynein, which hydrolyzes ATP to provide the energy needed for movement. Dynein is responsible for producing the sliding motion between microtubule doublets, causing cilia and flagella to bend and generate movement.
What motor molecule is associated with the microtubules in cilia and flagella?
Dynein is the motor molecule associated with the microtubules in cilia and flagella. Dynein is responsible for generating movement by sliding the microtubules past each other.
Dynein and kinesin are?
Dynein and kinesin are motor proteins that move along microtubules within cells to transport various cargoes. Dynein typically moves towards the minus end of microtubules, while kinesin moves towards the plus end. They play crucial roles in intracellular transport, cell division, and maintaining cell structure.

What is the molecule that allows kinetochores to walk down the kinetochore microtubules?
The molecule that allows kinetochores to 'walk' down kinetochore microtubules during cell division is dynein. Dynein is a motor protein that moves along microtubules towards their minus end, helping to transport the chromosomes towards the cell poles.
Dynein and kinesin are?
Dynein and kinesin are motor proteins that move along microtubules within cells to transport various cargoes. Dynein typically moves towards the minus end of microtubules, while kinesin moves towards the plus end. They play crucial roles in intracellular transport, cell division, and maintaining cell structure.
What moves cell parts along microtubule?
Motor proteins, such as kinesin and dynein, move cell parts along microtubules by utilizing energy from ATP hydrolysis to generate mechanical force. Kinesin generally moves cargo towards the cell periphery, while dynein moves cargo towards the cell center.
The tubular part of the cytoskeleton?
The tubular part of the cytoskeleton is called microtubules. They are dynamic structures composed of tubulin protein subunits that provide structural support, help in intracellular transport, and are essential for cell division. Microtubules also serve as tracks for motor proteins like dynein and kinesin to move along within the cell.
How cilia and flagella bend?
you should refer to a sliding microtubule model. in this model, there is a "9+2" structure or pattern, along with spokes, motor proteins and a basal body. the spokes connect to the 2 microtubules in the center and the motor protein, dynein, connects the 9 pairs to each other. dynein "walks" one microtubule pair relative to the other. if they weren't fixed in place at either end, they would move past each other. they are fixed at one end by attachment to the basal body, which is attacked just inside the plasma membrane. therefore the walking motion pulls the microtubule pairs over (while spokes contribute to the lack of free movement). keep in mind that dynein requires energy. it binds, releases and moves, binds, releases and moves. (think of a cat climbing a tree.)

Is tubulin a motor protein?
No, tubulin is not a motor protein. It is a structural protein that helps form microtubules, which are important for cell structure and transport. Motor proteins, on the other hand, are responsible for moving cellular components along microtubules.
