Mitochondrion
 Outer Membrane -layer of phospholipids
 Inner Membrane -more permeable than outer membrane
 Intermembrane space -between the outer and inner membranes
 Cristaelayers of inner membrane folds that increase surface area.
 Matrix site of Kreb’s cycle
 Ribosome -site of protein synthesis
 mDNA -DNA found only in mitochondria
25  ATP Synthase -enzyme that makes ATP from ADP

Mitochondrion
 Matrix site of the Kreb’s cycle
