bacterial flagellum

bacterial flagellum

[bladimadrigal]

This is absolutely amazing, as a mechanic I always thought that moters were completely lifeless until I realized that these have been since the inception of biology

[academiadaeletricidade]

I’ve no words for this! As an electrical engineer who works in a hydroelectric power plant and see generators for 20 years I’m astonished!!!

00:01 Bacterial flagella are helical motorized structures that bacteria use to move through their environment.
00:39 The bacterial flagellum consists of a filament, hook, and basal body.
01:11 The bacterial flagellum remains stationary and derives its power from a proton gradient.
01:50 The molecular mechanism of rotation in bacterial flagellum is not known.
02:22 Flagellar assembly begins with the formation of the MS ring.
03:01 The rotor and flagellar proteins make up the extracellular portion of the flagellum.
03:35 The bacterial flagellum is assembled through a cylindrical structure with the help of cap proteins.
04:16 Proteins assemble to form the bacterial flagellum

kudos to the cameraman who shrunk to even smaller than a bacteria

[Numinus_Arts]

I’ve worked on turbofan engines for 10 years In the military and to see that bacteria already did it without all the complicated engineering blows me away

[craigbikes]

I'm still having trouble wrapping my mind around the idea that something organic can rotate 360 degrees without being directly attached to the body

Some intelligent entity is giving us a Tech demo.

[grahammcdonald]

When you think we invented motors, but nature got there first

[cheepsht]

I wonder if anyone has built a large scale version and tested the design on a boat. Now that would be interesting. We know that Leonardo Devinchi used to copy designs found in nature.

[muhammadwaxali]

And now we’re essentially creating the same thing in AI. Guess nature had us beat by a long shot though. Intelligent design

[damonhackney]

Very lucid explanation-even to a layman. I learned about the flagellar motor last night and it's been blowing my freaking mind today.

Magnificent presentation. Thanks! Recent studies have shown that Mot A - Mot B can move horizontally under the force of a C ring conformation change whilst still spinning in the same direction under the proton motive force. This simple change of position changes the direction of spin of the rotor almost instantaneously to cause a tumble or a change in direction from forward to backwards.
The spiral alignment of individual flagellin proteins makes spin direction of the flagellum a critical factor in direction of motion and speed with reverse being 50% faster.
A new book published by Austin Macauley Publishers titled From Chemistry to Life on Earth outlines abiogenesis in great detail with a solution to the evolution of the genetic code and the ribosome as well as the cell in general using 290 references, 50 illustrations and several information tables with a proposed molecular natural selection formula with a worked example for ATP.

FINALLY, I FOUND THE BEST FLAGELLA VIDEO! THANKS! xxx it was beautiful!

[JordanBeagle]

4:50 So billions of proteins are dancing in me at any second 😄

[cesarg.e.]

Es increible como se produce y desoues como se mueve 👏👏gracias por el video .

[marcolarussa]

Fascinating. Specially when i read the comments from engineers that are shocked by how this works. Thanks for the video!

[LittleLiilyyy]

How incredible His creation is. It’s so exciting being able to explore further into His work.

[gilmarjunior]

"Yeah that evolved spontaneously" 💀

[ropao]

Seems to me like the most plausible explanation for this is intelligent design. It’s called irreducible complexity. Darwin cannot explain how all this came together if he suggests a gradual slow process of multiple small changes to reach the present organism. How could this small machine work without all the pieces being assembled together at the same time? You can build a car engine gradually but you can’t drive it until it’s complete.

[dimai]

I can't believe that people will still deny the creator after watching this.
