Song about mitochondria

Dave sez, "Continuing on with my summer goal to periodically write songs about scientific terms, I bring to you what I'm assuming is the only song ever about mitochondria, and quite likely the only song ever to attempt to rhyme 'endosymbiotically' with 'maternally'. Altogether on the chorus now, 'Mitochondria... Mitochondria... Mitochondria... Mitochondria...'"

Quite possibly the only song dedicated to mitochondria, ever! (Thanks, Dave!)
