Actin Myosin Molecular Crossbridge Animation

The linked animation above shows the molecular interactions that occur within the skeletal muscle sarcomere between actin and myosin during skeletal muscle contraction.


Legend

  • Moving blob and stick - myosin complex.
  • Moving blob and stick - myosin complex with ATPase activation.
  • Ball binding myosin and splitting - ATP losing a phosphate to form ADP.
  • Twisted string of beads - actin helix.
  • Blue string - tropomyosin.
  • Beads stacked on large bead on blue string - troponin.
  • Small ball binding troponin - Calcium ion (Ca2+).
  • Grey pyramid - Magnesiun ion (Mg2+).
