What else can I help you with?
Protein strands that attach to the centromere region during M-phase of cell cycle?
During Metaphase the protein strands that attach to the centromere region are called spindle fibres.
What structure make blood cells and provide muscles to attach?
the correct answer is bone.
When sponge buds attach to the parent a what forms?
when sponge buds attach to its parent, a colony forms! next time, dont use this website, you'll will have to wait for a long time for your answer. just go to www.google.com thats where i found this answer -----HMalhi :)
What do clamps attach to in science?
it happens because it helps to keep the beaker stable with no shaking
What is correct position of seating In chair?
To lay on it as in the way as your back attach with it at 0 degree.
What protein with heads that attach in cross bridging?
myosin
During skeletal muscle contraction myosin cross bridges attach to active sites of?
During skeletal muscle contraction myosin cross bridges attach to active sites of actin filaments. Actin filaments bind ATP. Their growth is regulated by thymosin and profilin.
Where do myosin cross bridges attach during muscle contraction?
Myosin functions as an ATPase utilizing ATP to produce a molecular conformational change of part of the myosin and produces movement. Movement of the filaments over each other happens when the globular heads protruding from myosin filaments attach and interact with actin filaments to form crossbridges. The myosin heads tilt and drag along the actin filament a small distance (10-12 nm). The heads then release the actin filament and adopt their original conformation.
During muscle contraction myosin cross bridges attach to which active sites?
actin filaments
What is needed to attach and detach myosin heads from actin?
For attachment of myosin heads to actin, calcium ions must bind to troponin, causing tropomyosin to move out of the way, exposing the binding site on actin. ATP then binds to the myosin head, leading to its activation and attachment to actin. For detachment, ATP is hydrolyzed, causing a conformational change in the myosin head that releases it from actin.
Myosin cross bridges attach to active sites of?
actin filaments in muscle cells during muscle contraction.
What are two myofilaments that slide past one another to allow muscle cells to contract?
The two myofilaments that slide past one another to enable muscle contraction are actin and myosin. Actin makes up thin filaments while myosin forms thick filaments. During muscle contraction, myosin heads attach to actin filaments and pull them towards the center of the sarcomere, causing the muscle to shorten.
What protein makes up the thick filaments of myofibrils?
Myosin makes up the THICK filaments, and actin makes up the thin filaments of myofibrils.
What are the proteins are involved in muscle contraction?
Actin and myosin
Why are the muscles of the finger don't develop as much force as the muscles of the leg?
1. Muscles fibers with a large diameter develop more force, and have more myofibrils and more myosin heads that can attach to actin. The amount of force is dependent on the number of myosin heads attached to actin.
What are the thick protein filaments in the cell made of?
The thick protein filaments in a cell are primarily made of a protein called myosin. Myosin filaments are involved in muscle contraction and various other cellular processes such as cell motility and cytokinesis.
What is the function of myosin?
Myosin is responsible for actin-based muscular mobility/contraction.
