1. Chem 3550 Lecture 10/18/2006 Chapter 14: Basic Concepts of Cellular Metabolism and Bioenergetics

3. Metabolism in Heterotrophic Cells

4. Multienzyme systems in metabolic pathways (Metabolons)

7. Structure of ATP

10. Catabolism of Ethanol (Biochemical Redox)

11. Group-Transfer Reaction -Phosphoryl transfer to ATP, Kinases catalyse similar reactions

12. Transfer of Acyl group

13. Hydrolysis Reactions

16. Nonhydrolytic Cleavage

17. Isomerization and Rearrangement Reactions

18. Bond formation (Ligation) -Uses ATP

19. Some Metabolic Reactions

21. Gibbs Free Energy(∆G) G = H - TS ∆G = ∆H - T∆S If ∆G is less than 0 (negative), the reaction is exergonic(spontaneous), energy released If ∆G is 0, reaction is at equilibrium If ∆G is greater than 0(positive), reaction is endergonic (Non spontaneous), energy consumed

23. Standard Free Energy ( ∆G o’ ) and K eq ∆G o’ = -2.303RT log K eq

24. Energy from ATP
