The role of calcium entry in cardiac excitation-contraction coupling was subsequently explained by the finding that calcium release from the cardiac SR, unlike that of skeletal muscle, depends on a small calcium influx across the plasma membrane in a process called âcalcium-triggered calcium releaseâ. 36 Calcium release from the cardiac SR, which causes localized âcalcium sparksâ that can be visualized when cells are injected with calcium-sensitive dyes, 37 38 is a critical ...
3. calcium binds to troponin. 4. the troponin-calcium complex induces a conformational change in the actin-tropomyosin interaction, allowing myosin to bind to actin. 5. the actin-myosin binding allows the S 1 unit to move to the âunstrainedâ position, causing muscle contraction.
