Dynein and MT's crossbridge

thanks very much for this, really helpful!

Thanks so much , now I understand how it works with two microtubules.

But there's one thing I can't understand. Usually one microtubules will both push and be pushed by its neighbors because of the arrangements. so technically, the flagella can't bend at all. Could you explain what happens in this case?

@naxava Check out the video on "How MT's are arranged in sperm" This will explain that flagella can bend due to the arrangement of the axoneme and the fact that the MT's are held together by a rubber band like protein called Nexin.

@matyboy247 Glad it helped. Thanks for checking out the video, Hopefully the other videos will be useful for you and your fellow students also.

Kinesin walks in the plus direction and dynein towards the minus end.  That is the only difference. Glad u like the video.

@af07e not always. kinesin-14 walks in (-)end direction.

Thank you for a very good explanation!

Could you explain the difference between dynein and kinesin? They are both motor proteins and need ATP for their movements.
