How Do Microtubules Move

Because the microtubule doublets in an axoneme are connected by nexin links, the sliding of one doublet along another causes them to bend, forming the basis of the beating movements of cilia and flagella.

How do microtubules transport?

Microtubules function as tracks in the intracellular transport of membrane-bound vesicles and organelles. This process is propelled by motor proteins such as dynein. Motor proteins connect the transport vesicles to microtubules and actin filaments to facilitate intracellular movement.

How do microtubules work?

Microtubules are stiff tubes, about 25 nm in diameter. During interphase, they serve as tracks on which organelles and the nucleus are positioned by molecular motor proteins. During mitosis, microtubules form a structure called the mitotic spindle which physically segregates the chromosomes into the two daughter cells.
