___________ are known as the powerhouse of the cell.

Mitochondria are known as the powerhouse of the cell. Mitochondria are organelles found in most eukaryotic cells, and they play a critical role in producing energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. This process involves breaking down glucose and other nutrients in the presence of oxygen to release energy. Mitochondria have their own DNA and are believed to have originated from ancient symbiotic bacteria that were engulfed by early eukaryotic cells. Their structure includes an outer membrane and an inner membrane with folds called cristae, where many of the enzymes involved in ATP production are located. This unique structure and function earn mitochondria the nickname “powerhouse of the cell.”
