Chapter 8 - Introduction to metabolism Objectives 1. Describe the function of enzymes in biological systems. 2. Explain enzyme specificity. 3. Explain the induced-fit model of enzyme function. 4. Describe the mechanisms by which enzymes lower activation energy. 5. Explain how substrate concentration affects the rate of an enzyme-catalyzed reaction. 6. Explain how temperature, pH, cofactors, and enzyme inhibitors can affect enzyme activity. 7. Explain how metabolic pathways are regulated. Key terms activation energy active site adenosine triphosphate (ATP) allosteric regulation anabolic pathway catabolic pathway catalyst chemical energy coenzyme cofactor competitive inhibitor cooperativity endergonic reaction energy energy coupling entropy enzyme-substrate complex exergonic reaction feedback inhibition first law of thermodynamics free energy heat induced fit kinetic energy metabolic pathway metabolism noncompetitive inhibitor order phosphorylated potential energy ribose second law of thermodynamics
