Expert Answer
The energy required fopr the various life processes comes from food that we eat, mainly carbohydrates, proteins and fats. These are broken down during digestion into simpler components and the energy released is stored in the form of energy molecules called ATP. ATP are stored in mitochondria.
The mitochondrion exist in every cell in the body. They are considered the cell's power plant, supplying the energy to carry out all of the cell's jobs. Each cell contains up to a thousand mitochondria. The mitochondrion produce ATP i.e. Adenosine triphosphate. It is believed to be our source of energy. ATP's main purpose is to transport chemical energy within cells for metabolism.
