Campbell's Biology, 9e (Reece et al.) Chapter 9 Cellular Respiration and Fermentation This is one of the most challenging chapters for students to master. Many students become overwhelmed and confused by the complexity of the pathways, with the multitude of intermediate compounds, enzymes, and processes. The vast majority of the questions in this chapter address central concepts rather than details of these pathways. Other questions have accompanying figures that provide details for reference and ask students to interpret or use these models. Overall, the emphases are on the inputs and outputs of each pathway, the relationships among these pathways, the cellular locations, redox as a central principle in respiration, and chemiosmosis.

Campbell's Biology, 9e (Reece et al.) Chapter 8 An Introduction to Metabolism This chapter lays the foundations for the chapters on respiration and photosynthesis. Key concepts are as follows: The laws of thermodynamics govern energy transformations by living organisms, metabolic reactions couple energy-harvesting reactions to reactions that accomplish cellular work, and enzymes increase the rates of reaction. Understanding the properties of enzymes, how they work, and how their activities are regulated is necessary to achieve an understanding of metabolic pathways. Multiple-Choice Questions 1) Which term most precisely describes the cellular process of breaking down large molecules into smaller ones? A) catalysis B) metabolism C) anabolism D) dehydration E) catabolism

1 B io F actsheet January 1998 Number 12 Respiration Aerobic respiration can be divided into four stages: 1. Glycolysis (G) 2. The Link reaction (LR) 3. Kreb?s cycle (K) 4. The electron transfer chain (ETC) These take place in different parts of the cell (Table 1) and the detailed biochemistry of these reactions is shown overleaf. Respiratory quotients The respiratory quotient (RQ) is defined as the ratio of carbon dioxide produced to oxygen consumed per unit time by an organism: volume of CO2 produced volume of O2 consumed Different substances give different RQ values Cellular respiration is the process by which the energy contained in organic molecules is made available for all of the active
