A mitochondrion is a double membrane bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have reduced or transformed their mitochondria into other structures. Mitochondria may have a number of different shapes. A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins. Because of this double-membraned organization, there are five distinct parts to a mitochondrion: The intermembrane space (the space between the outer and inner membranes) The cristae space (formed by infoldings of the inner membrane) The matrix (space within the inner membrane)
