Cheat Sheet
- Metabolic Pathways: Catabolism vs Anabolism -
Catabolic pathways break down large molecules into smaller units, releasing energy, while anabolic pathways consume that energy to build complex biomolecules (Campbell Biology). A handy mnemonic is "Catabolism C for Cutting" and "Anabolism A for Adding" to keep them straight. Mastering this distinction is essential in chapter 8 an introduction to metabolism.
- Gibbs Free Energy and Spontaneity -
The change in free energy (ΔG = ΔH - TΔS) predicts whether a reaction is exergonic (ΔG < 0) or endergonic (ΔG > 0), as detailed in Lehninger Principles of Biochemistry. Remember "Happy Hands Tell Stories" to recall ΔG = ΔH minus TΔS. This formula underpins energy flow concepts in chapter 8 introduction to metabolism.
- ATP Structure and Energy Coupling -
Adenosine triphosphate (ATP) stores energy in its high-energy phosphate bonds; hydrolysis (ATP + H₂O → ADP + Pi + ~7.3 kcal/mol) drives endergonic processes (MIT OpenCourseWare). Think "ATP is the cell's rechargeable battery" to visualize energy coupling. Recognizing ATP's role boosts your mastery of AP Biology metabolism quiz topics.
- Enzyme Function and Kinetics -
Enzymes lower activation energy via an induced-fit model, binding substrates at the active site and accelerating reaction rates (NCBI). The Michaelis-Menten equation, V = (Vmax [S])/(Km + [S]), describes enzyme kinetics - Km indicates substrate affinity. Noting that enzyme names end in "-ase" helps you quickly identify catalysts in metabolic pathways.
- Regulation: Feedback Inhibition & Allosteric Control -
Cells regulate metabolic flux through feedback inhibition, where the end product binds an upstream enzyme, and allosteric regulators shift enzyme activity (Nature Reviews Molecular Cell Biology). For example, citrate inhibits phosphofructokinase in glycolysis to prevent overproduction. Understanding these controls is crucial for acing chapter 8 ap bio metabolism quiz questions.
