Lessons
- 1Energy, Thermodynamics and ATPThe first and second laws of thermodynamics in living systems, entropy and free energy, exergonic and endergonic reactions, energy coupling through ATP, redox reactions and the electron carriers NAD⁺, FAD and NADP⁺.10 questions
- 2Aerobic Cellular RespirationThe four stages of aerobic respiration and where they happen: glycolysis, pyruvate oxidation, the Krebs cycle and the electron transport chain with chemiosmosis; ATP yield accounting, efficiency, and how to detect the products of respiration in the lab.11 questions
- 3Fermentation, Other Fuels and Metabolism in SocietyHow cells keep making ATP without oxygen, how fats and proteins feed into respiration, how respiration is regulated and poisoned, and how people use microbial and human metabolism in food, fuel, clean-up and health.11 questions
- 4PhotosynthesisChloroplast structure and pigments, the light-dependent reactions (photosystems, photolysis, chemiosmosis, cyclic and noncyclic flow), the Calvin cycle, photorespiration with C4 and CAM adaptations, how photosynthesis and respiration fit together, and how to detect its products in the lab.12 questions
