How does the sliding filament theory work

WebDec 21, 2024 · The sliding filament theory describes the mechanism that allows muscles to contract. According to this theory, myosin (a motor protein) binds to actin. The myosin then alters its configuration, resulting in a “stroke” that pulls on the actin filament and causes it to slide across the myosin filament. What is the sliding filament hypothesis? WebApr 12, 2024 · Once attached, the myosin heads pull the actin filaments and cause the myofibrils to slide past each other. This process shortens the sarcomeres and hence, the …
