Can myosin attach to the cytoskeleton
WebQUESTION 3 If actin interacted with myosin normally, but could not attach to the rest of the cell’s cytoskeleton or membrane, in what phase of contraction would the effect take place? a. Excitation b. Coupling c. Contraction d. Not in a specific phase, but still important to muscle activity e. Not relevant or couldn't happen WebFeb 1, 2024 · Since the myosin chains in the thick filament are attached to it, they remain stationary as well. Imagine the left and right Z line (disk), which anchor the actin thin filaments, moving towards the center line as the actin thin filaments slide along the stationary myosin thick filaments. This contracts the sarcomere.

WebApr 14, 2024 · Our data shows that in mitotic cells integrins are not linked to the cytoskeleton by talin and vinculin, leading to reduced cell–ECM adhesion strengthening, while β1 integrins and different... WebMore cytoskeleton, Mitosis. 1. Diagram how microtubule sliding changes the shape of cilia and flagella. 2. Describe how microfilaments and their associated myosin motor proteins can create cellular movement. 3. Describe how the placement and binding between intermediate filaments provide structural support for membranes. 4.
WebThese bands are then in series with whatever force is being applied on the muscle and transmit this force onto the attached actin. Therefore, whenever the myosin detaches, due to the traction on actin, it moves a little to its original position, allowing the cycle to continue.

WebWell, it is not technically correct to say that cytoskeleton is involved in DNA replication, rather a cytoskeleton plays the role during mitosis and meiosis by reorganizing chromosomes. Microtubules bind chromosomes during metaphase and then in anaphase pull them apart (so both poles of cells - future daughter cells - get set of chromosomes).
