Details of pathway sequences, energetics, regulation and significance of the following: Glycogen Metabolism (Glycogenesis/Glycogenolysis), glycolysis(including the entry of glycogen, fructose, galactose and other hexoses into the pathway),Tricarboxlic acid (TCA) cycle (including detailed treatment of the pyruvate and ketoglutarate dehydrogenase complexes and their regulation), Pentose Phosphate Pathway (PPP), gluconeogenesis and the cori cycle, , electron transport chain (ETC) and oxidative phosphorylation. Disorders of carbohydrate metabolism.
