Topics:

10. Cellular Metabolism
    • What are coupled reactions?
    • What is the role of ATP in coupling the cell's anabolic and catabolic processes?
    • How does chemiosmosis function in bioenergetics?
    • Fermentation and cellular respiration
    • How do catabolic pathways break down organic molecules?
    • What is the role of oxygen in energy-yielding pathways?
    • How do cells generate ATP in the absence of oxygen?
    1. Describe principals of energy conservation
       1. Cells must recycle of ATP
       2. Coupled oxidation and reduction reactions release energy
    2. Describe the process of cellular respiration
       1. Describe process of glycolysis, where it occurs in the cell, and the amount of energy released
          • Substrate-level phosphorylation
       2. Describe process of Krebs cycle, where it occurs in the cell, and the amount of energy released
          • Chemiosmosis
       3. Describe process of electron transport system, where it occurs in the cell, and the amount of energy released
    3. Fermentation: an alternative pathway
       • Wine and beer production
    4. Describe bacterial cellular metabolism
       • Chemotrophic bacteria and vent communities

Time Range:
6 days

Suggested Teaching Strategies:

• Students will read and take their own notes on the chapter (maybe in outline form)
• Lecture over redox reactions
• Lecture on substrate-level phosphorylation, and chemiosmosis
• Lecture on glycolysis, fermentation and bacteria generation of energy
• Lecture on Krebs cycle and electron transport system
• Students will fill out crossword puzzle that uses terms from the chapter
• Students will fill out chapter study guide to complement their lecture and board notes
• Students will fill out worksheet on glyolysis, Krebs cycle, and electron transport chain
• Critical Thinking: Students will use computer and do activity on 9.0 thru 9.4 on Cell Respiration on CD Rom from Campbell's Biology
