Mitochondria

Explanation:

They have the enzymes (and own DNA) required to turn ADP into ATP using electrochemical gradients across their inner membranes. This potential energy drives an enzyme called ATP synthase after a long chain of reactions (link, Krebs and oxidative phosphorylation) and also takes oxygen and turns it into water by adding electrons to it.
Hope that helps! Please ask for more clarification if necessary.
