Definitions:

Mitochondria

Mitochondria are organelles within cells that are responsible for producing adenosine triphosphate (ATP), the cell's main energy carrier, through the process of oxidative phosphorylation.

ATP

Adenosine triphosphate, a molecule that carries energy within cells for metabolism.

Mitochondria

Organelles found in the cytoplasm of eukaryotic cells, involved in producing energy through the process of cellular respiration.

Peroxisomes

Organelles found in virtually all eukaryotic cells that are involved in the catabolism of very long-chain fatty acids, branched-chain fatty acids, D-amino acids, polyamines, and the reduction of reactive oxygen species - specifically hydrogen peroxide.
