Question

Quizplus · Accepted Answer

Mitochondria contain their own DNA, which is separate from the cell's nuclear DNA. They have a double membrane structure, consisting of an inner and outer membrane. The inner membrane is folded into structures known as cristae, which increase the surface area for chemical reactions. Mitochondria are often referred to as the cell's power plants because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.
