How Does Molecular Motors : Kinesin, Dynein and Myosin (Animation) Work?

Molecular motors are tiny workers inside your body that help move things around like a team of little trucks.

Imagine you're playing with toy cars on a track. Each car has its own path and knows where to go, some go forward, some go backward. That’s kind of how kinesin, dynein, and myosin work. They’re like these tiny toy cars that move things along roads inside your cells.

Think of kinesin as a car that moves forward on a track, it’s like the little truck going from one end of the room to another. It carries cargo, like a backpack full of supplies, and walks along tiny tracks called microtubules, which are like the roads in your cell.

Now think of dynein as a car that moves backward, it’s like walking from the end of the room back to the start. It also carries things, but it uses different roads or paths in the cell.

Myosin is like your friend who helps you move things around in the playground, it helps muscles contract so you can run and jump!
