Final answer:
The organelles that produce ATP in eukaryotic animal cells are called mitochondria and they function as the cell's energy factories. Mitochondria use the chemical energy from glucose and other nutrients to generate ATP in a process called cellular respiration.
Step-by-step explanation:
The organelles that produce ATP in eukaryotic animal cells are called mitochondria. Mitochondria are often referred to as the "powerhouses" or "energy factories" of the cell because they are responsible for generating adenosine triphosphate (ATP), which is the cell's main energy-carrying molecule. Mitochondria use the chemical energy from glucose and other nutrients in a process called cellular respiration to produce ATP. This process requires oxygen and produces carbon dioxide as a waste product.
