Infinitely more interesting than Mitochondria being "the powerhouse of the cell" is the fact that it has its own DNA separate from your DNA, because billions of years ago the ancestor of all eukaryotes had a symbiotic relationship with a species of bacteria and it sort of got embedded in it.

It'd be like if a billion years from now boxer crabs and sea anemones evolved into a single organism with 2 sets of DNA (4 sets including two different mitochondrial DNAs)

Sleep may not just be rest for the mind—it may be essential maintenance for the body's power supply. A new study by University of Oxford researchers, published in Nature, reveals that the pressure to sleep arises from a build-up of electrical stress in the tiny energy generators inside brain cells. The discovery offers a physical explanation for the biological drive to sleep and could reshape how scientists think about sleep, aging, and neurological disease.

"Okay, so around four years ago, I wrote an article on parasites, and in that little piece I dropped a bomb… or well… something I considered a bomb. Namely, that mitochondria (fondly referred to as the powerhouse of the cell) probably started off as bacteria or intercellular parasites that were essentially engulfed by nucleated cells, and have, since then, become an essential component of our cellular structure. Why is this a bomb, you might ask? Well, our science textbooks never told us that the organelle responsible for essentially keeping us alive (through energy production) was/is a parasite we just happened to form a symbiotic relationship with some two billion years ago?! It’s crazy."
