  1. Bioenergetics I. Introduction A. Definition B. History

  2. 1. Ludwig Boltzman late 19th century, proposed energy existed as packets based on particles he called atoms, started fields of thermodynamics and kinetics. Committed suicide in 1906 because no one believed him. 2. Albert Einstein late 1905 atoms held the energy (basis for almost all energy equations) 3. Ernest Rutherford (1910) and Niels Bohr (1912) would design the shape and structure of an atom. Tragic that Boltzman never saw his science proven.

  3. C. Energy Flow

  4. 1.6CO2 + 6H20 + Energy C6H12O6 + 6O2 The basis for life on earth is bound to this diagram.

  5. 2.Oxidation/Reduction Reactions Reduction/oxidationthe complete donation and receiving of electrons, hydrogen atoms or ENERGYbetween two molecules Page 100

  6. D. Energy Forms

  7. 1. Potential vs. Kinetic Energy Figure 5.1

  8. E. Laws of Thermodynamics

  9. 1. First Law = Law ofConservationor Quantityof Energy 2. Second Law = Law ofOrder or Qualityof Energy

  10. F. Predicting Energy Directions

  11. a. Exergonic Reactions= release energy to the environment b. Endergonic Reactions= absorb energy to cool the environment

  12. G. ATP

  13. 1.ATP (Adenosine triphosphate) Structure Figure 5.3

  14. 2.ATP Cycling Figure 5.4

  15. H. ATP Coupling

  16. 1.How ATP is used by cells? Figure 5.5

  17. 2.Energy flow by cells? Figure 5.6

  18. I. Making ATP

  19. 1.Direct Phosphorylation

  20. 2.Oxidative Phosphorylation

  21. J. Enzymes

  22. 1. Structure Figure 5.8

  23. 2. Function Figure 5.10

  24. 3. Regulation Figure 5.9

  25. K. Electron Carriers

  26. 1. NAD+and 2. FAD+are used in all organismsduring cellular respiration. 3. NADP+ is only used in the photosynthetic processes so it is found in blue-green monerans,protistan alga's,and plants.
