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
