Myofilament actine
WebIn muscle cells, actin filaments are aligned and myosin proteins generate forces on the filaments to support muscle contraction. These complexes are known as ‘thin filaments’. In non-muscle cells, actin filaments form a track … Web1. the activated myosin head binds to actin, forming a CB 2. ADP is released and myosin slides the thin filament toward the center of the sarcomere 3. ATP binds to the myosin head and detaches it from actin 4. ATP is hydrolyzed to ADP and P and the energy released re-cocks the myosin head
