What cell part preforms animal respiration?

Animal respiration primarily occurs in the mitochondria, which are often referred to as the "powerhouses" of the cell. Mitochondria are responsible for producing adenosine triphosphate (ATP) through aerobic respiration, utilizing oxygen to convert glucose into energy. This process involves a series of biochemical reactions, including the Krebs cycle and the electron transport chain. Thus, mitochondria play a crucial role in energy production for cellular activities.
