Biochem Review. Test 2 Oxidative Metabolism a) Catabolism : energy production by degradation of carbohydrates, lipids, and proteins b) Anabolism : is the synthesis of macromolecules c) ΔG˚ = standard free energy at 1atm and pH of 0 d) ΔG˚’ = standard free energy (frequently used in biochemistry) where pH is 7, and equals –RT ln  K’eq Def: portion of the total energy available for useful work . Relation to Keq: if Keq is determined for a reaction, then the standard free energy change for that rxn can also be calculated. e) Pyruvate dehydrogenase regulation: Many components can be phosphorylated, which inactivates them (in this case) f)

g) Anapleurotic reaction : intermediates can also be synthesized (under severe conditions) from other molecules (Amino Acids).

h) Examples of Energy Rich compounds: 1,3 diphosphoglycerate, phosphoenol pyruvate, acetyl CoA, acetyl phosphate, and Adenosine Triphosphate i) Types of mitochondrial electron acceptors: Fe-S clusters, Hemes, and Uniquinone (Coenzyme Q) j) Mammalian Electron transport chain: 1) Complex I ( NADH dehydrogenase )-primary function is to strip electrons from NADH; can independently pump protons into intermembrane space. Types of electron acceptors: Fe-S and FMN 2) Complex II ( Succinate Dehydrogenase )-strips electrons from FADH 2 . Types of e- acceptors: Fe-S and B type Heme 3) Both complex I and II produce electrons which are sent to
