What is the structure of a mitochondrion?
copied from wikipedia A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins.[5] The two membranes, however, have different properties. Because of this double-membraned organization, there are five distinct compartments within the mitochondrion. There is the outer mitochondrial membrane, the intermembrane space (the space between the outer and inner membranes), the inner mitochondrial membrane, the cristae space (formed by infoldings of the inner membrane), and the matrix (space within the inner membrane).
