Eukaryotic organelles such as mitochondria and quantasomes possess the oxysomes and the quantasomes respectively.
The oxysomes are small round bodies present in the inner folding of the inner mitochondrial membrane (cristae). These small particles are also known as F-1, F-0 particles, or the Fernandez Moran particles. They play important role in the electron transport chain and ATP production.
Quantasomes are protein and lipid-containing particles present in the chloroplasts and are play an important role in photosynthesis and are considered as the unit of photosynthesis.
