The “Big Ideas” of AP Biology: In each unit, consider how these themes relate to what you learn.
1 - The process of Evolution drives the diversity and unity of life
2 - Biological systems utilize free energy and molecular building blocks to grow and to maintain dynamic homeostasis
3 - Living systems store, retrieve, transmit and respond to information essential to life
4 - Biologic systems interact, and these systems and their interactions possess complex properties
Chapter 6: A Tour of the Cell
1. Why are cells small?
2. Briefly describe the structure and functions of the cytoskeleton, with focus on its role in cell division.
Chapter 40.1. – Animal form and function
1. What are constraints on animal size and shape?
2. What are some general roles of interstitial fluid?
3. How is the body organized? What are the main functions of the organ systems of mammals?
4. What are the four different types of animal body tissues?
Chapter 12: The Cell Cycle
1. Describe the functions of cell division.
2. Using a typical animal cell as an example, describe the complete cell cycle, including all of the stages of interphase,
mitosis, and cytokinesis.
3. Compare and contrast the cell cycle in plants and animals. In prokaryotes and eukaryotes.
4. Briefly describe the regulation of the cell cycle in terms of the three cell cycle checkpoints including the roles of
cyclins and Cdks (ex. MPF)
5. Describe what happens when the cell cycle is not properly regulated.
Chapter 11: Cell Communication
1. What are uses of local and long-distance signaling between cells in prokaryotes? In eukaryotes?
2. What is an example of a plant hormone? An animal hormone?
3. Describe the three stages of cell signaling.
4. How does testosterone activate cells? [Note: this is a model that we can generalize, since many cell signals result in
activating or inhibiting transcription of specific genes.]
5. Detail the function of G protein-coupled receptors, receptor tyrosine kinases, and ion channel receptors
6. What are protein kinases? Describe the effects of a signal transduction cascade (shown in Fig. 11.9)
7. What are the roles of second messengers like cAMP, calcium ions, and IP3?
8. Describe how cell signals initiate nuclear and cytoplasmic responses.
9. What is apoptosis? Why do organisms need this process?
Section 18.5: Cancer
Study Guide: Interactive Q’s 18.9, Multiple Choice 9, 10, 11, 13, 21
1. What is the role of viruses in cancer?
2. What are oncogenes and how are they related to proto-oncogenes?
3. How do mutations in the ras gene contribute to cancer? What kind of protein is encoded by ras?
4. How do mutations in p53 gene contribute to cancer? What kind of protein is encoded by p53?
5. What is meant by the multistep model of cancer development?
6. How does genetics contribute to cancer?
