The Bacterial Flagellum

Is this video posted anywhere else where the audio has not been disabled?

The flagellum has a bias to spin clockwise, once attractants activate the Che Phosphorelay system Che Y makes the motor turn counterclockwise. This is one of the fundamentals of Chemotaxis.

How is it possible for anyone to know how this works when we can't see it that close? I don't understand? People have made this computer model of a bacterial flagellum over and over again but why can't anyone show us a real one that close?

[eklipst2x]

Yes. I want to know how we know this.

Does anyone know whose singing in this video?

[silvgunsuperman]

the song is idiot kings by soul coughing

[adrifromhh]

This video didnt nearly explain how the flagellum works...

[silvgunsuperman]

there is a proton gradient on one side of the membrane, making them want to come to the other. the flood of red dots coming in represents the protons flowing down their gradient. they come through the flageullum and spin it much like water would be used to generate hydroelectricity. the flagellum utilizes this flow to do work, i.e. spin and move the bacterium

[DebeoMorium]

Thats not entirely true. It usues Proton motive force. Which does use H+ ions, but its the static electric charge creating the force. While the chemicals do also move around following a gradient its the static charge of the ions doing the pulling and not the fricion of the material itself. So its more like an electric motor than a water powered device.

thanks

i wish there was a reference link to download it

could life be perfect? :)
