Description

Enzymes & Metabolism (Chapter 6) • Define metabolism. • Differentiate between catabolic and anabolic pathways. • Define energy and differentiate kinetic energy from potential energy. • Describe the First and Second Laws of Thermodynamics and apply them to living things. • Describe free energy (G). • Differentiate exergonic and endergonic chemical reactions using descriptions and/or graphs. • Describe the structure of ATP and explain why ATP is an ideal molecule for energy storage. • Explain how cells use ATP to do work and how they get new ATP. • Define catalyst and enzyme. • Define the active site of an enzyme. Describe the interaction of the active site with the substrate and subsequent formation of products. • Describe, and identify in a graph, the activation energy of a chemical reaction. • Describe how enzymes speed up chemical reactions. How are activation energy (EA) and ΔG affected by enzymes? Identify graphs of catalyzed vs. non-catalyzed reactions. • Differentiate competitive and non-competitive inhibitors. • Describe allosteric regulation....
