DETAILED NOTES ON MUSCLE BOND

To initiate muscle contraction, tropomyosin has to show the myosin-binding web site on an actin filament to allow cross-bridge formation concerning the actin and myosin microfilaments. The first step in the process of contraction is for Ca++ to bind to troponin to ensure that tropomyosin can slide from the binding web-sites on the actin strands.Thi
