Mitochondria are really one of our cells' most under appreciated organelles and the consequences of them being "the powerhouse" are a lot more profound than you might think. I highly recommend Nick Lane's book on them, Power, Sex, Suicide: Mitochondria and the meaning of life, which explores the consequences of the biochemistry, population genetics, of mitochondria for how animals live in general. It's far more interesting than biochemistry has any right to be, along with his other books.
