Part 1. Cellular Respiration Prarthana Minasandram Partner: Ben Liu Introduction Purpose: To examine the rate of alcoholic fermentation using various carbohydrates. Hypothesis: If the yeast is placed in 5% glucose or sucrose solutions‚ then carbon dioxide production will increase over time. If boiled yeast is placed in a 5% sucrose solution‚ then carbon dioxide production will remain constant. Variables Independent variable: Carbohydrate solutions (5% solutions of glucose and sucrose) and

Unit 2. Chapters 9-16. Cell Processes 1. Cellular Respiration‚ Photosynthesis‚ Cell Cycle‚ Mitosis‚ Meiosis‚ & Genetics. Note A: All work must be hand-written‚ including charts & diagrams. Note B: each answer requires more than one sentence & use diagrams whenever possible; failure to use diagrams will result in less points. Chapter 9 Outline 1) Principles of Energy Conservation a) Cellular respiration and fermentation are catabolic(energy – yielding) pathways b) Cells must recycle the ATP

In the process of cellular respiration‚ there are three main parts; Glycolysis‚ Krebs Cycle‚ and Electron Transport Chain. All three of these processes form together to make cellular respiration happen‚ and that gives our bodies energy to do the work that we need to perform every single day. Without cellular respiration‚ our bodies would not have enough energy to perform everyday tasks‚ let alone live and survive. The first process‚ glycolysis‚ starts with a few molecules of glucose. There are

1. What is life? Life is the state of a material‚ complex or individual‚ characterized by the capacity to perform certain functional activities which include metabolism‚ growth‚ reproduction‚ and some form of responsiveness and adaptation. 2. What are the characteristics of living things? Organization Homeostasis Metabolism Growth Adaptation Response Reproduction 3. Create a table with two columns with the headings living and non-living and place the following under the appropriate columns

Chapter 9 Study Guide 1. Explain the difference between aerobic respiration and fermentation. Fermentation is partial degradation of sugars that occurs without oxygen. Aerobic respiration consumes organic molecules and oxygen and yields ATP. 2. Diagram for photosynthesis and respiration 3. What are redox reactions? What is the difference between reduction and oxidation reactions? Redox reactions are chemical reactions that transfer between reactants. In oxidation‚ a substance loses

Chapter 1 Revision Questions 1) List three abiotic characteristics and briefly describe the main differences between aquatic and terrestrial environments. Abiotic characteristics are: Temperature‚ Pressure and Light Availability. The differences between aquatic and terrestrial environments are: Small temperature changes occur in aquatic environments while large temperature changes occur in terrestrial environments. As the depth of water increases‚ pressure increases in aquatic environments while
