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.

Chapter 9?Energy in a Cell Section 1?The Need for Energy Chemical bonds store energy that can be released when the bond is broken. Some bonds have more energy than others. Cell Energy Plants and other producers are able to trap light energy from the sun. Consumers obtain their energy from producers and other consumers. Cells need energy for active transport, cell division, movement and protein production, transport and storage. Your muscles and organs need energy to work. Energy is stored, at the cellular level, in the bonds of a molecule in your cells that any organelle can use. Adenosine triphosphate (ATP): composed of an adenosine molecule with three phosphate groups attached

Photosynthesis Energy Transformations ATP is the energy molecule used in all living things, so supplies must be constantly replenished. energy must be added to make ATP, thus ATP formation is an endergonic reaction. ADP + P + energy ---? ATP the addition of a phosphate molecule to ATP is called phosphorylation ATP ---? ADP + P + energy the removal of a phosphate molecule from ATP gives off energy and is called dephosphorylation Electron Transport System (ETS) is the means by which energy production occurs within cells. It is a series of progressively stronger electron acceptors. Each time an electron is transported, energy is either released or absorbed. This is how most of the ATP in plants and animals is formed Redox Reactions

Cellular Respiration Plant cells harvest energy from the sun, and store it as glucose. That glucose must be transformed into energy the cell can use, specifically ATP. This takes place in the mitochondria of cells. There are two ways that a cell can harvest energy from the food (glucose) it takes in: Anaerobic Cell Respiration (Fermentation) ? glucose metabolism in the absence of oxygen that produces 2ATP molecules and either ethanol or lactic acid. Involves 2 stages: Glycolysis Fermentation Aerobic Cellular Respiration ? glucose metabolism with oxygen that produces 36 ATP molecules, CO2 and H2O. Involves 4 stages: Glycolysis Pyruvate oxidation Krebs cycle Electron transport and chemiosmosis Stage 1 ? Glycolysis

Collins Collins Assignment 1 Begin your first experiment by developing a hypothesis to predict what will happen to oxygen consumption in the reaction flask after the addition of pyruvate. Develop a second hypothesis to predict how oxygen consumption will change in the flask upon the addition of pyruvate and ADP.
