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.

Chemical Reactions and Stoichiometry Chapter 8 Balancing Chemical Reactions (Wednesday 1/5/11 P1,3,5 & Thursday 1/6/11 P2,4,6)? Indicators of a Chemical Reaction ? evidence of a chemical reaction Evolution of heat and light (simultaneously) Production of a gas (bubbles, odor change) Formation of a precipitate (solid, cloudy) Color change (not introduced by an outside source such as dye or ink) Characteristics of a Chemical Reaction ? the atoms in one or more reactant rearrange when bonds are broken and/or created to produce one or more new products with different properties than the reactants had before the reaction. Reactants - on the left? react to one another and/or their environment. Products ? on the right of the reaction ? produced/created from reactants.

Carbohydrates Robert J Sturgeon, Heriot-Watt University, Edinburgh, UK The carbohydrates comprise one of the major groups of naturally occurring organic molecules and are amongst the most abundant constituents of plants, animals and microorganisms. In general, carbohydrates are polyhydroxy-aldehydes or-ketones. They may contain, in addition, amino, acetamido and carboxyl functional groups. Introduction The term carbohydrate includes monosaccharides, oligo- saccharides and polysaccharides. Also included are sub- stances derived from monosaccharides such as alditols, which are derived by reduction of the carbonyl group and carboxylic acids, which are derived by oxidation of one or more terminal groups. Replacement of a hydroxyl group with a hydrogen atom produces a deoxy-sugar and
