Mitochondria structure Isolated in 1948 for the first time Double membrane system Outer membrane – contains porins Inner membrane – high concentration of cardiolipin Intermembrane space – chemically equivalent to cytosol Matrix – enzymes involved in Kreb’s cycle Cristae – serve to increase surface area
