Unit Objectives

  • Cell Biology
    • Compare the relative size of various cells through modeling activity (agar cells) and microscopy; explain why cells remain small and identify tools of cellular study in biology.
    • Identify the structure, composition, and function of cell organelles through a self-guided activity.
    • Compare and contrast the structures of eukaryotic and prokaryotic cells through self-guided activity.
    • Compare and contrast the structures of plant and animal cells through self-guided activity.
    • Identify major structural components of the cytoskeleton.
  • Cell Membranes
    • Identify the components of the fluid mosaic model of the cell membrane through a modeling activity.
    • Compare isotonic, hypertonic, and hypotonic solutions, and predict the path of water and solutes in given examples through a lab.
    • Describe how solute size and molar concentration affects the process of diffusion through a selectively permeable membrane, through a lab.
    • Relate osmotic potential to solute concentration and water potential through a lab.
    • Describe the effects of water gain or loss in plant and animal cells through a lab.
  • Enzymes
    • Distinguish between ender/exergonic reactions in terms of spontaneity and reaction delta G; anabolic and catabolic pathways; potential and kinetic energy and open/closed systems.
    • Describe the first and second laws of thermodynamics and relate them to reaction coupling.
    • Describe catalase in terms of its function in chemical reactions and substrate/product relationships through a lab.
    • Model enzyme function as in terms of active site, substrate, product, activation energy and catalysis (through toothpickase); induced fit, competitive and noncompetitive inhibition, reversible, irreversible and allosteric and feedback inhibition (through toothpickase and student-designed modeling). Describe the role of irreversible inhibition in poisoning.
    • Identify and characterize the changes to reaction rate produced by changes in temperature, pH, enzyme concentration and substrate concentration. through a lab and modeling activity.
  • Cell respiration and fermentation
    • Relate structure of mitochondria to their function.
    • Write the summary equation for respiration, and compare to the reaction for photosynthesis.
    • Identify the major components of ATP and the role of energy-containing bonds in the structure of ATP.
    • Sequence the events of cell respiration, including major reactants and products of glycolysis, oxidation of pyruvate, the CAC and OxPhos, as well as major reactions, through a modeling exercise.
    • Compare the end products of aerobic and anaerobic respiration through a lab (yeast lab, possibly looking at yeast selectivity of food sources) and modeling exercise.
    • Understand the role of electron carriers in respiration.
    • Compare the efficiency of substrate-level phosphorylation to oxidative phosphorylation (and later to photophosphorylation).
    • Collect and interpret data related to the effects of temperature and germination on respiration rate and explain why oxygen consumption can be used to measure the rate of respiration through a controlled experiment.
