Cross bridge cycle vs sliding filament theory
WebAnswer: A walk along theory can explain how activated actin filament and the myosin cross-bridges interact to cause contraction. When myosin head attaches to an active site, the head tilts automatically toward the arm that is dragged along the actin filament. What is sliding filament theory? At... WebMay 13, 2024 · The thin actin filaments also have binding sites for the myosin heads—a cross-bridge forms when a myosin head binds with an actin filament. The process of cross-bridge cycling is shown in Figure \(\PageIndex{6}\). A cross-bridge cycle begins when the myosin head binds to an actin filament. ADP and P i are also bound to the …
