Chapter 6 metablolism An organism's metabolism transforms matter and energy Metabolism, metablolic pathway, catabolic, anabolic, bioenergetics, Forms of energy, (chemical) potential, kinetic, thermal, 1st and second law of thermodynamics, biological order, Free energy change of a reaction tells us whether ofr not the reaction occurs spontaneously free energy, delta G, stability and equilibrium,endergonic, exergonic, ATP powers cellular work by coupling exergonic reactions to endergonic reactions ATP energy coupling Hydrolysis of ATP does work, Phosphorylated intermediate, ATP regeneration, enzymes speed up metabolic reactions by lowering energy barriers Activation energy free energy delta G unaffected by enzyme, catalysis, enzyme, active site, substrate, enzyme substrate complex, effects of temp range, and pH range, cofactors, coenzymes,competetive inhibition,noncompetitive inhibition(allosteric), and activation, cooperativity,feedback inhibition (more causes less, less causes more)
