Mitochondria and chloroplasts are the energy-processing organelles of eukaryotic cells. Both
organelles contain outer and inner membranes. The inner membrane of the mitochondrion
contains many folds. The chloroplasts have a third membrane forming the thylakoids.
Molecules such as enzymes responsible for the synthesis of ATP are embedded in the inner
membrane of the mitochondrion and the thylakoid membrane of the chloroplast.
