NOT KNOWN FACTS ABOUT MUSCLE BOND

To initiate muscle contraction, tropomyosin has to show the myosin-binding site on an actin filament to allow cross-bridge development involving the actin and myosin microfilaments. Step one in the whole process of contraction is for Ca++ to bind to troponin to ensure tropomyosin can slide clear of the binding internet sites to the actin strands.Th
