NADH is oxidized into NAD , H ions, and electrons by an enzyme. FADH2 is also oxidized into H ions, electrons, and FAD. As those electrons travel farther through the electron transport chain in the inner membrane, energy is gradually released and used to pump the hydrogen ions from the splitting of NADH and FADH2 into the space between the inner membrane and the outer membrane (called the intermembrane space), creating an electrochemical gradient. Webcristae formed as curved cylinders of uniform diameter [11], others may exhibit flat or even prismatic cristae.
