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.

AP Biology Lab #2 Enzyme Catalysis Overview: In this lab you will observe the conversion of hydrogen peroxide (H2O2) to water and oxygen gas by the enzyme catalase, and then measure the amount of oxygen generated. You will also calculate the rate of an enzyme-catalyzed reaction. Objectives: Before doing this lab, please review the following from your text and/or notes: Structure, function of enzymes How temperature, pH, enzyme concentration and substrate concentration affect the initial reaction rates of enzyme-catalyzed reactions Review the terms: Catalyst Catalase Catalysis After doing the lab, you should be able to:

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.

Chapter 9: Cellular Respiration, Harvesting Chemical Energy The principles of energy harvest Cellular respiration and fermentation are catabolic energy yielding pathways Cells recycle ATP they use for work Redox reactions release energy when electrons move closer to electronegative atoms Electrons ?fall? from organic molecules to oxygen during cellular respiration The ?fall? is stepwise during respiration via NAD+ and an electron transport chain The process of cellular respiration Respiration involves glycolysis, Krebs cycle and electron transport Glycolysis harvests chemical energy by oxidizing glucose to pyruvate The Krebs cycle completes the energy yielding oxidation of organic molecules

Analyses Osmosis and Diffusion Osmosis and Diffusion are processes of passive transport. In this lab we studied the basic concepts of molecular movement in solutions. During the execution of the experiment, I became aware that molecules are in constant motion and tend to move from areas of higher concentration to those of lower concentration. Diffusion is the movement of molecules following that concentration gradient. It occurs on the diverse states of matter. Osmosis refers to the specialized diffusion of molecules of water through a selectively permeable membrane.

Inquiring About the World of Life Biology is the science of life Traditionally divided into three divisions: - Botany - Zoology (NOT Zoo-ology!) - Microbiology 3 Modern Biology Many diverse subdivisions, such as: - Wildlife Biology - Cellular Biology - Anatomy & Physiology - Ecology - Genetics - Evolutionary Biology - Molecular Biology - Developmental Biology - Immunology - Behavioral Ecology - Marine Biology 4 - asking questions and seeking science-based answers The central activity of biology: scientific inquiry Biologists ask questions such as: how a single cell develops into an organism - how the human mind works - how living things interact in communities Biology is therefore a quest ? an ongoing inquiry about the nature of life

9.1: Catabolic pathways yield energy by oxidizing organic fuels. Redox reactions: oxidation and reduction. The stages of cellular respiration. In redox reactions the loss of e- from one substance is called oxidation. The gain to the other is known as reduction. The harvesting of energy from glucose by cellular respiration is a cumulative function of three metabolic stages: Catabolic pathways and production of ATP Organic compounds possess potential energy because of the arrangement of electrons in bonds between atoms. Compounds that participate in exergonic reactions can act as fuel. Enzymes help cells degrade complex organic molecules that are rich in potential energy. This breakdown can provide energy to
