MEET THE MIGHTY MITOCHONDRION
Every jump, sprint, and heartbeat needs energy. Inside your cells, tiny organelles called mitochondria act like rechargeable batteries. They take the food you eat and, with help from the oxygen you breathe, convert it into usable energy. Without these power plants, your muscles could not move and your brain could not think. They are among the most important structures in the entire animal kingdom.
⚡ DID YOU KNOW?
The word mitochondrion comes from Greek words meaning "thread" and "granule." Under a microscope, early scientists saw them as tiny threads and dots scattered through the cell.
