Chemical energy is converted to mechanical energy by motor proteins.
The force-dependent movement of motor proteins, including as myosins and kinesins, along cytoskeletal filaments is fueled by the hydrolysis of ATP molecules. Molecular motors called motor proteins move along the cytoskeletal filaments of the cell by hydrolyzing ATP. They provide a variety of tasks for biological systems, such as facilitating intracellular trafficking along biopolymer filament tracks and regulating filament sliding during muscle contraction.
