How and why can virtually all organisms-plants, animal, and bacteria - use the exact same energy molecule, ATP?

All organisms, plants, animals, and bacteria are all biotic factors (living things), and every living thing has to have cells. Within cells there are organelles. Some organelles are ribosomes, endoplasmic reticulum, mitochondria, nucleus, etc ... Mitochondria houses ATP, and all eukaryotic cells (cells with a nucleus) have mitochondria.
