Question

Quizplus · Accepted Answer

All three statements are correct. Motor proteins, such as myosin, kinesin, and dynein, undergo a conformational change to move along the cytoskeleton. This movement is powered by the hydrolysis of ATP, which provides the energy for the conformational change. As they move, motor proteins also bind to the cytoskeleton, allowing them to traverse along it and cause movement.
