Chapter 8 Metabolism
8.4 Enzymes
Activation energy
lowered by enzymes
Active site
binds to specific substrates
Optimal temp and pH
Inhibitors
Competitive inhibitors: bind to activation site
Noncompetitive inhibitor: binds to a different site on the enzyme
8.1 Matter and energy
Metabomism
metabolic pathways
Anabolic: building
Catabolic: breaking down
Energy
Thermal: motion of atoms
Heat: thermal energy in transfer
Potential: location/ structure
Chemical: molecule structure
Law of thermodynamics
1st law: energy cannot be created nor destroyed
2nd law: spontaneous processes increase entropy
8.2 Spontaneous reactions
Free Energy
Reactions
Exergonic: spontaneous
Endergonic: nonspontaneous
8.3 Coupling
exergonic - endergonic
phosphorylated intermediate
ATP
hydrolysis yields ADP and free energy
catabolic pathways regenerate ATP from ADP
8.5 Enzyme activity
Allosteric regulation: affects the shape of an enzyme
Cooperativity: binding can stimulate activity elsewhere
