Unformatted text preview: Chemistry 233 Fundamentals of Biochemistry Energy Transfers Energy Transfers in Metabolism Topics Thermodynamics, very briefly entropy free energy Equilibrium constants ∆ G o ' coupled reactions Entropy the measure of disorder of a system high disorder → high entropy highly ordered → low entropy Disordered states are more probable Second Law of Thermodynamics: “The universe tends toward maximum disorder.” PUZZLERS: relate the concept of entropy to the structure of water if the universe tends to states of higher disorder, how do biological systems maintain the high degree of order necessary for Life? Free Energy Concept of Gibbs Free Energy: J. Willard Gibbs, 1878 ∆ G = ∆ H - T ∆ S favorable vs unfavorable reactions ∆ G < 0 reaction is favorable (energy released) ∆ G = 0 reaction is at equilibrium ∆ G > 0 reaction is unfavorable (energy required) hence ∆ S > 0 will favor a more negative ∆ G ∆ S < 0 will favor a more positive ∆ G overall, ∆ G depends on the relative magnitudes of ∆ H and T ∆ S Example:...
