      Keep in mind that acetylcholine do not enter in the sarcomere , it remains at neuromuscular junction or motor end plate.

    How does the myosin head pull the actin inwards? Is there some conformational change in a protein leading to shortening or something?

    • @hydrothermalworm7778
      @hydrothermalworm7778 2 года назад +6

      The myosin motor domain is what's doing the ATP hydrolysis. Myosin with no ATP bound is locked to the actin filament. ATP binds the myosin head, causes conformational change in both the head and lever arm, releasing the head from the filament and swinging it forward. ATP is hydrolyzed into ADP + Pi, which causes another conformational change in the head, increasing its affinity for actin, causing it to bind to the actin filament again, this time forward from where it was at the beginning. Pi is released, which causes the lever arm to return to its original position, pulling on the actin filament as it does so. ADP is then released, and another ATP binds the myosin head to release it and start the cycle over.

    If we strap our hand to a machine which helps us move our hand move in and out and we let loose of it then how is it moving because we aren't sending neuro signals meaning the sites of bonding are still closed how is the muscle still contracting then??????

    There at the end..my muscles are not able to relax back. It's hell. On any activity when I finally get loose (usually in water floating and stretching) it takes only a few minutes and i get super tight again. I had t9t10 damage in spinal. Got one leg paralyzed but I was, am able to get that leg working after 3.5 years. My muscles in legs an glute are so tight, but I get them loose with hours of work and water..yet to feel them get so tight I can't walk after 100 yards. My Drs are clueless and really don't give a dam..
