How fast does biological chemistry happen?

Click For Summary
The discussion centers on the speed of individual reactions in biological processes, particularly in the context of muscle contractions and motor proteins. The initial comparison to a boxer practicing jabs highlights the rapidity of these reactions. A clarification is made regarding the GIF, which is identified as depicting a motor protein transporting a vesicle along a microtubule, rather than illustrating muscle contraction, which involves actin and myosin. An animation is referenced to further explain these concepts visually.

I've seen this before, but it boggles my mind when I try to put it in the context of a boxer practicing his jabs.
Just how fast are these individual reactions occurring?

(Did I get he right GIF? It's supposed to be the one of muscles contracting.)

Looks like a motor protein pulling a vesicle along probably a microtubule, not a muscle contraction, which would be actin and myosin.
Here's an animation:

Thread 'Magnetoreception in Animals'
For more than a hundred years people have been intrigued by how animals are able to do certain navigating tasks so well. Being able to sense magnetic fields has been one of several clues animals could use to figure out where they should go. Among possible magnetic sensory mechanisms have been: light sensitive proteins (cryptochromes) in the retina that can also react to magnetic fields. Microscopic magnetite crystals on found in various areas of the body (often the nose near nerves) A new...
