Mitochondria provide the energy a cell needs to move, divide, produce secretory products, contract - in short, they are the power centers of the cell. They are about the size of bacteria but may have different shapes depending on the cell type. Mitochondria are membrane-bound organelles, and like the nucleus have a double membrane. The outer membrane is fairly smooth. But the inner membrane is highly convoluted, forming folds called cristae. The cristae greatly increase …showed first 75 words of 391 total…

So every time a muscle contracts, chemical energy is converted into kinetic energy. In short, mitochondria is the primary benefactor of the human body, it not only provide energy for cells to submerge from place to place but it also a base projector for all energy given off the human body.
