The mitochondria is a cellular organelle that is known as the powerhouse of the cell. Mitochondria provide the energy that cells require to divide, move, and contract.
Mitochondria exist in the shape of an oblong oval-like structure which tend to be roughly the size of a bacteria. Mitochondria have folds called cristae that increase the surface area of the internal structure.
Inside the mitochondria sugar is broken down with the addition of oxygen in order to produce ATP. ATP is the energy currency used in organisms.
