Gleit filament theorie

WebThe sliding filament theory begins with the release of calcium ions from a specialized organelle in the muscle fiber called the sarcoplasmic reticulum, as described in statement (3). Calcium ions bind to tropomyosin, causing it to pull away from and expose these myosin binding sites on the actin filament, as described in statement (2). ... WebStep 2: Calcium ions cause tropomyosin to unblock actin-binding sites and permit cross bridges to form between actin filament and myosin head. Step 3: Myosin head utilises ATP to pull on actin filament toward the line. Step 4: Sliding of actin filaments past myosin strands results in shortening of sarcomeres.
