5 Thermodynamics Energy changes First Law of Thermodynamics Second Law of ThermodynamicsHow does this apply to humans?
6 Free Energy The energy Available to do work Delta G= Delta H- TDelta S H= enthalpy which is the energy contained in the chemical bonds of a substanceT= temperature kelvinS= entropy or the energy unavailable due to disorder
7 Endergonic vs Exergonic If Positive Delta G then the reaction is endergonicIf Negative Delta G then the reaction is evergonic
8 Activation EnergySpontaneous Chemical Reactions Require activation energyCatalysts
9 You down with ATP???? The energy currency of cells Hydrolysis drives endergonic reactionsATP cycles continously
10 Enzymes Biological Catalysts Ligand vs Substrate Active Sites Are they all proteins?
11 MultiEnzyme Complex Sounds familiar…. 3 advantages Increases the frequency with which the enzyme collides with the substrateEliminates the possibility of unwanted reactionsAll reactions take place within the complex can be controlled as a unit
