Welcome to Module 4

Welcome to Week 4!

In this week's chapter, we will review how cells harvest chemical energy. Topics include photosynthesis and the stages of ATP production in the human body.

Mastering assignments for this chapter include reading Chapter 6, completing Chapter 6 homework, the Dynamic Study Module Quiz, and the interactive lab on enzymes. There are video tutorials in the reading and homework assignments. Chapter 6 will be the last chapter for our midterm exam. I will discuss the midterm exam with the class in the next unit.

Please review the module learning objectives as a study guide for the Dynamic Study Module Quiz and the midterm exam.

As always, if you have any questions, please do not hesitate to contact me.

Sincerely,

Dr. Burke

Module Learning Outcomes

Upon successful completion of this module, you will be able to:

Cellular Respiration: Aerobic Harvesting of Energy

6.1 Compare the processes and locations of photosynthesis and cellular respiration. Explain why it is accurate to say that life on Earth is solar-powered.

6.2 Explain how breathing and cellular respiration are related.

6.3 Provide the overall chemical equation for cellular respiration. Compare the efficiency of this process in cells with the efficiency of a gasoline automobile engine.

6.4 Explain how the human body uses its daily supply of ATP.

6.4 Define a kilocalorie (kcal) and relate it to a food calorie.

6.5 Explain how the energy in a glucose molecule is released during cellular respiration.

6.5 Explain how redox reactions are used in cellular respiration.

6.5 Describe the general roles of dehydrogenase, NAD+, the electron transport chain, and oxygen in cellular respiration.

Stages of Cellular Respiration

6.6–6.11 Compare the reactants, products, and energy yield of the three stages of cellular respiration.

6.6‑6.11 List the cellular regions where glycolysis, the citric acid cycle, and oxidative phosphorylation occur. Note whether substrate-level phosphorylation or chemiosmosis occurs.

6.12 Explain how brown fat is specialized for heat production and when brown fat is most active. Describe the evidence that suggests that brown fat is present and functioning in many adult humans.

6.13 Identify the total possible yield of ATP molecules per glucose. Explain why the number of ATP molecules cannot be stated exactly.

Fermentation: Anaerobic Harvesting of Energy

6.14 Compare the reactants, products, and energy yield of alcohol fermentation and lactic acid fermentation. Distinguish between obligate anaerobes and facultative anaerobes.

6.15 Describe the evolutionary history of glycolysis.

Connections Between Metabolic Pathways

6.16 Explain how carbohydrates, fats, and proteins are used as fuel for cellular respiration. Explain why a gram of fat yields more ATP than a gram of starch or protein.

6.17 Explain how nutrients are used in biosynthesis.
