Microfilaments, also known as actin filaments, and myosin work together to promote movement in cells. Microfilaments play a crucial role in changing the shape of the cell and in movement by forming contractile rings and directing the movement of organelles within the cell. Myosin is a motor protein that uses ATP to generate force and move along the microfilament tracks, pulling the cell in the desired direction. While microtubules and intermediate filaments are important in maintaining the cell's shape and providing structural support, they do not play as direct a role in cell movement as microfilaments and myosin do.
