Mitochondrion, organelle found in most eukaryotic cells, the primary function of which is to generate energy in the form of adenosine triphosphate. Mitochondria also store calcium for cell signaling activities, generate heat, and mediate cell growth and death. Most people understand mitochondria function in regard to energy production. Learn how mitochondria function in cell death and regeneration. Their main function is to generate the energy necessary to power cells , but they are also involved in cell signaling and death. Present in nearly all types of human cells, mitochondria are vital... Learn about mitochondria in cells. Get the definition and mitochondrion diagram. Learn about the structure and functions .
