First step of sliding filament theory

WebAccording to his theory, filament sliding occurs by cyclic attachment and detachment of myosin on actin filaments. Contraction occurs when the myosin pulls the actin filament … WebSep 24, 2024 · The sliding filament theory explains how muscles contract based on muscle proteins sliding past each other to generate force. The theory states that Actin and Myosin form a cross-bridge which allows them to slide past each other while remaining at a constant distance. …
