Why mitochondria are known as powerhouse of the cell?

Mitochondria are double membrane bound organelles inside a cell. They produce the energy that the cell requires for its day to day cellular processes. This energy is produced in the inner membrane of the mitochondria in the form of ATP which acts as a currency of energy inside the cell. Due to this energy producing function of the mitochondria, it is called the power house of the cell.
