Mitochondria

Mitochondria are the site of aerobic respiration. Aerobic respiration produces ATP a molecule easily broken down to release the energy needed for metabolic reactions.ATP is an immediate energy store.Very active cells usually contain a lot of mitochondria.Mitochondria are organelles that have a double membrane.The inner membrane is highly folded. The infoldings are called cristae. They are filled with a fluid called the matrix.There is a single loop of double-stranded DNA in the matrix (mtDNA).Mitochondria can make their own proteins and replicate.
