Unit 4 at a glance new curriculum

  1. 1. Unit 4. Cell Energetics (12 days) Textbook Readings • Chapters 9, 10 Lecture Topics 2.a.1 All living systems require constant input of free energy. 2.a.2 Organisms capture and store free energy for use in biological processes. Laboratory Exercises • AP® Biology Laboratory 5: Cell Respiration [C8] [C4] o Goal: To determine the rate of oxygen consumption in dry and germinating pea seeds at two different temperatures (wet lab) • AP® Biology Laboratory 4: Plant Pigments and Photosynthesis [C8] [C4] o Goal : To use paper chromatography to separate the pigments in a leaf; to calculate Rf values, to investigate the relationship to light intensity, light wavelength, and temperature on photosynthesis (wet lab) Chapter 9: Cellular Respiration Oxidation vs. reduction Electron transport chain Glycolysis (summary only) Citric acid cycle (summary only) Cytochromes Chemiosmosis Fermentation (alcohol vs. lactic acid) Fermentation vs. respiration Chapter 10: Photosynthesis Chloroplast structure Overall reaction Light reactions (photosystem I vs. photosystem II) Chemiosmosis in chloroplast vs. mitochondria Calvin cycle (summary only) C4 plants and photorespiration CAM plants
