OBJECTIVES

Chapter 5: Cell Division

1. Describe how species maintain a characteristic chromosome number. (overview of chromosomes, mitosis and meiosis)

2. Describe how mitosis distributes a complete set of chromosomes to each of the daughter cells. Be able to explain the cell cycle, its regulation and the stages and variations of mitosis.

3. Describe how meiosis reduces the chromosome number in life cycles involving sexual reproduction. Be able to explain the stages of meiosis and ways to increase genetic variation.

4. Compare and contrast mitosis with meiosis.

5. Describe the roles of mitosis and meiosis in the human life cycle.

6. Science Focus: p. 84, How much of a eukaryotic chromosome is protein? What is the job of histone proteins/nucleosomes? What is the difference between heterochromatin and euchromatin?

7. Bioethical Issue: p. 95, What are the risks associated with women delaying childbirth until their 30s and 40s? (There are 4 different potential consequences.) If delaying pregnancy means increased health and fertility problems, should insurance companies pay for the extra costs associated with such pregnancies?

Chapter 6: Metabolism: Energy and Enzymes

8. Describe the different types of energy, laws of thermodynamics and the concept of entropy.

9. Describe the different types of reactions and the structure and function of ATP.

10. Describe the role of enzymes in chemical reactions, factors that effect their efficiency, and ways to regulate their activity.

11. Explain how oxidation-reduction reactions occur in cells and discuss the overall equations for photosynthesis and aerobic cellular respiration. Be sure to include the role of chloroplasts and mitochondria in the flow of energy through living things.

12. Ecology Focus: p. 110, Why Do Leaves Change Color in the Fall: 1) Why do leaves appear green even when other pigments are present in the leaves? 2) Describe the two reasons why the chlorophyll breaks down. 3) What is the advantage of having several pigments present in leaves? 4) Why does the red/purple color (pigments: anthocyanin) develop later and why are there different shades of red?

13. Bioethical Issue: p. 112, Eat Your Enzymes!: 1)Name three reasons to take enzyme supplements. 2) Name three reasons not to take enzyme supplements. 3) Should manufacturers of enzyme supplements be required to complete controlled medical research studies before selling their product?

Chapter 7: Cellular Respiration

14. Give an overview of aerobic cellular respiration and name/describe each of the four phases required.

15. Describe the reactants, products and processes of glycolysis.

16. Describe the structure of a mitochondrion and state where each phase of cellular respiration occurs. Describe the last three phases of cellular respiration in detail including their reactants and products.

17. Calculate the energy yield of aerobic cellular respiration per glucose molecule.

18. Describe and give examples of the two parts of your metabolism: catabolism and anabolism.

19. What is fermentation and how does it differ from aerobic respiration?

20. Bioethical Issue: p. 127 ,Illegal Cyanide Fishing: 1) Biochemically, how does cyanide kill fish? 2) How do fishermen expose the fish to cyanide? 3) What is getting destroyed as well?

Chapter 8: Photosynthesis

21. Explain how all life is dependent upon the capture of solar energy and the structure of a chloroplast.

22. Describe the process of the capture of solar energy by plants (light-dependent reactions of photosynthesis) using photosystems. Be sure to discuss both the cyclic and noncyclic electron pathways.

23. Describe the Calvin Cycle and the course of carbohydrate synthesis (light-independent reactions of photosynthesis).

24. Discuss some of the other aspects of photosynthesis: its role in food production, protection of life, and modifications of the process in C4 and CAM plants.

25. Compare and contrast photosynthesis with cellular respiration. Fig 8.13

26. Ecology Focus: p. 142 So Why is Photosynthesis Important to Me? 1) Name the two big reasons why heterotrophs like us are dependent on plants. 2) Name four other reasons plants are important to us.

27. Bioethical Issue: p. 144 Food for the Human Population: 1) What is one of the most worrisome threats to food security? 2) How can GM foods have a positive impact? Negative impact? 3) Do you approve of a measure to limit population growth? Why or why not?
