WebImage credit: OpenStax Biology. Motor proteins use energy in the form of ATP to “walk” along specific cytoskeletal tracks. They are essential for movement of vesicles and other cargoes within cells, as well as for the movement of muscle and cilia/flagella: Myosin is associated with actin microfilaments and is required for movement of muscle. WebMar 22, 2024 · These proteins, as their name suggests, actively move cytoskeleton fibres. Hence, chemicals and organelles are distributed throughout the cell.
