What is the name of the organelle found i animal cells whose function is energy production?

The organelle found in animal cells responsible for energy production is called the mitochondrion (plural: mitochondria). Mitochondria generate adenosine triphosphate (ATP), which serves as the primary energy currency of the cell, through processes such as cellular respiration. They are often referred to as the "powerhouses" of the cell due to this critical role in energy metabolism.
