How fast does biological chemistry happen?

AI Thread 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 'New Alzheimer's Treatment Clears Plaques From Brains of Mice Within Hours'

I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
