Complexity of metabolism
Review of Energy:Energy
*kinetic energy*potential energy
Free energy, stability, work capacity and changeFree energy
Change in free energy =DG
Gravitational Motion
Diffusion Chemical Reaction
Free energy, stability, work capacity and changeEquilibrium
*chemical equilibrium
DG = 0, no net change in the system
Chemical reactions with free energy changes:
*energetically favorable *energetically unfavorable
Metabolic Disequilibrium
*Multistep open hydroelectric system
EnzymesEnzymes speed up metabolic reactions:
Enzymes
Enzymes are catalytic proteinsEnzymes lower the barrier of EA
EnzymesInduced Fit
Enzymes: How they work
EnzymesPhysical and chemical properties affect enzyme activity:
*inhibitor
*cofactor
*coenzyme
*activators
ATPMain types of (cellular) work:
*mechanical*transport*chemical
ATP
