Quick Answer. Calcium is a crucial part of muscle contraction. The ionic element is released from muscles during contraction and relaxation. The release of calcium helps propagate the muscle contraction and relaxation stages.
1 Thin filaments in smooth muscle do not contain troponin. 2  calcium does not bind to troponin but, rather, to a protein called calmodulin. 3  The calcium-calmodulin complex 'activates' myosin which then binds to actin & contraction (swivelling of cross-bridges) begins. TROPONIN-Troponin molecules have binding sites for calcium ions. 2  When a calcium ion fills this site it causes a change in the shape and position of TROPONIN. 3  And, when TROPONIN shifts, it pulls the TROPOMYOSIN to which it is attached.
