How fast does biological chemistry happen?

In summary, the speed of chemical reactions in biological systems can vary greatly and can be influenced by factors such as temperature, pH, concentration of reactants and enzymes, and the presence of inhibitors or activators. Enzymes act as catalysts to speed up the rate of reactions by lowering the activation energy. The speed of biological chemical reactions can be measured using various techniques and is crucial for maintaining homeostasis and overall health in living organisms.

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:
