Two accredited biologists I know confirmed for me that the following is pretty much accurate (except for the colorization to show the separate parts.) It is a far cry from how cells were drawn in my high school textbook. Astounding. You are trillions of these little factories ...
One of my favorite parts are the "walking" motor proteins engaged in transport along protein tracks. A kinesin molecule can take up to 100 steps per second, covering per step.

By the way, please look for my new book toward the end of this year, which touches on these and countless other amazing phenomena that let you be you. It is being published by the Essentia Foundation, led by philosopher Bernardo Kastrup ...

This is a single human cell. The white filament-like structures are microtubules, and the small colored particles are ribosomes. Your body contains on the order of ~37 trillion cells. Each cell functions like a highly organized, self-regulating factory operating continuously. There is no central “supervisor”—yet thousands of processes run in parallel with remarkable coordination. Every ribosome is constantly building proteins by linking amino acids together. In eukaryotic (human) cells, a ribosome typically adds about 5–10 amino acids per second (not ~20). Since a single cell can contain millions of ribosomes, protein production is massive—resulting in millions to tens of millions of peptide bonds formed per second per cell. The microtubules act as an internal transport network. Motor proteins such as kinesin move along these tracks, carrying cellular cargo. They “walk” step by step using ATP, at speeds of roughly 500–1000 nanometers per second. Each cell contains a dense network of these filaments, with many motor proteins moving simultaneously.
