Copyright ? 2011 Pearson Education, Inc. - 1 - Name_______________________Period___________ Chapter 9: Cellular Respiration: Harvesting Chemical Energy Overview: Before getting involved with the details of cellular respiration and photosynthesis, take a second to look at the big picture. Photosynthesis and cellular respiration are key ecological concepts involved with energy flow. Use Figure 9.2 to label the missing parts below. See page 163 of your text for labeled figure. Concept 9.1 Catabolic pathways yield energy by oxidizing organic fuels 1. Explain the difference between fermentation and cellular respiration. Fermentation is a partial degradation of sugars or other organic fuel that occurs without the use of oxygen.

Chapter 23: The Evolution of Populations This chapter begins with the idea that we focused on as we closed the last chapter: Individuals do not evolve! Populations evolve. The Overview looks at the work of Peter and Rosemary Grant with Gal?pagos finches to illustrate this point, and the rest of the chapter examines the change in populations over time. As in the last chapter, first read each concept to get the big picture and then go back to work on the details presented by our questions. Don?t lose sight of the conceptual understanding by getting lost in the details! Overview The Smallest Unit of Evolution ?One misconception is that organisms evolve, in the Darwinian sense, during their lifetimes

Chapter 43 The Immune System Overview: Reconnaissance, Recognition, and Response Barriers help an animal to defend itself from the many dangerous pathogens it may encounter. The immune system recognizes foreign bodies = ?not self? and responds with the production of immune cells and proteins. Two major kinds of defense have evolved: innate immunity and acquired immunity. How do immune cells of animals recognize foreign cells? 1.5 ?m Innate immunity is present before any exposure to pathogens and is effective from the time of birth. It involves nonspecific responses to pathogens. Innate immunity consists of external barriers plus internal cellular and chemical defenses.
