Mitochondria Summary

Mitochondria

• Mitochondria are organelles found in all living cells except bacteria or archaea.
• They produce adenosine triphosphate (ATP), the main energy molecule used by the cell.
• Mitochondria are referred to as “the powerhouse of the cell”.
• Almost all cells, except prokaryotes, have mitochondria and rough endoplasmic reticulum.
• Aerobic respiration occurs in mitochondria.
• Cells with high rates of metabolism require a large number of mitochondria to provide sufficient energy.
