Molecular Motors: Structure and Function

This lecture explores the structure and function of molecular motors, focusing on translational motors like myosin, kinesin, and dynein, as well as their comparison with man-made motors in terms of size, fuel, speed, and efficiency. The instructor discusses the dynamics of molecular motors, their enzymatic nature, and the coupling of chemical and mechanical dynamics. The lecture delves into the movement of translational motors along tracks, the motor speeds, and the step size of myosin. Additionally, it covers the sliding motion of sarcomeres driven by myosin and the intracellular transport by kinesin and dynein.
