Presentation Transcript

  1. Oxidative phosphorylation Biochemistry, 4th edition, RH Garrett & CM Grisham, Brooks/Cole (Cengage); Boston, MA: 2010 pp 592-629 Instructor: Kirill Popov

  2. The mitochondrion Electron transport Oxidative phosphorylation Heat, oxidative stress, etc.

  3. *Numbers of subunits in the bacterial equivalents in parentheses. #Cytochromec is not part of an enzyme complex; it moves between Complexes III and IV as a freely soluble protein.

  4. The P/O ratio is an index of the efficiency of coupling P/O ratio: number of molecules of Pi incorporated (=ATP synthesized) per atom of oxygen consumed (or pair of electrons being carried through the chain). Measurements: oxygen consumption during complete phosphorylation of a fixed amount of ADP after addition of either an NAD+-linked substrate or FAD-linked substrate. P/O  2.5 for NADH P/O  1.5 for FADH2

  5. *The number depends on which shuttle system transfers reducing equivalents into the mitochondrion.
