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.

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.

Define metabolism. The totality of an organism?s chemical reactions, consisting of catabolic and anabolic pathways, which manage the material and energy resources of the organism. 2. There are two types of reactions in metabolic pathways: anabolic and catabolic. a. Which reactions release energy? catabolic b. Which reactions consume energy? anabolic c. Which reactions build up larger molecules? catabolic d. Which reactions break down molecules? catabolic

Vocabulary Entropy- a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system Catabolism- the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy; destructive metabolism. Anabolism- the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy; constructive metabolism. Cellular Respiration- the metabolic processes whereby certain organisms obtain energy from organic molecules Glycolysis- the breakdown of glucose by enzymes, releasing energy and pyruvic acid.

Cellular Respiration?An Overview 1 Cellular Respiration?An Overview What are the phases of cellular respiration? Why? All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in envi- ronments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this

Glycolysis Worksheet ? Answer Sheet 1. Explain why the phosphate end of ATP stores potential energy. Each of the phosphate groups is negatively charged. These negative repel each other and so they would have less energy if they were further apart. 2. Which has more potential energy, ATP or ADP? ATP has more potential energy than ADP since it has three negatively charged phosphates held together vs only two in ADP. 3. Write the overall reaction for cellular respiration. Glucose + 6 O2 6 CO2 + 6 H2O (+ energy in the form of ATP and heat) 4. What atom is known as an ?electron grabber? because it attracts electrons so strongly? oxygen 5. What is an electron transport chain?

Name: ______________________ Class: _________________ Date: _________ ID: A 1 Test on Energy and Metabolism--Chapters 7 and 8 Multiple Choice Identify the choice that best completes the statement or answers the question. ____ 1 An endergonic reaction can proceed only if it absorbs: A. less free energy than was released by a coupled endergonic reaction. B. the same amount of free energy that is absorbed by the enzymatic breakdown of proteins. C. energy from ADP, forming ATP. D. less free energy than is released by a coupled exergonic reaction. E. more free energy than is released by a coupled exergonic reaction. ____ 2 If one continues to increase the temperature in an enzyme-catalyzed reaction, the rate of the reaction: A. decreases and then levels off.
