Learning Guide: Cellular Respiration Bill Activity #28A To Think About: How do living things produce and use energy to survive in an ecosystem? In what ways do living things create matter to survive in an ecosystem? How do communities interact within their environments that result in the movement of matter and energy? 1st Interact: Watch Mr. Andersen’s Video on Cellular Respiration and take notes. 2nd Read and Record Key Terms/ Explain: Cellular Respiration and Fermentation Pgs. 163-183 Campbell’s Biology 9th edition Here is a list of key terms and concepts you will hear about and see during the lecture, podcast and chapter reading. Create a 2 column note structure to list the terms and definitions/information for each one. (They are listed vertically in order of the processes involved, color code the three processes/associated terms as we did with the note packet) Key Terms Aerobic respiration Cellular respiration Cellular respiration eq. Redox reactions Oxidation Reduction NAD/NADH Substrate-level phosphorylation Glycolysis Oxidation of Pyruvate to Acetyl coA Citric acid cycle Oxidative phosphorylation Electron transport chain Cytochromes Chemiosmosis Obligate anaerobes Facultative anaerobes ATP synthase Proton motive force Fermentation Alcoholic fermentation Lactic acid fermentation Explain 1. The process of glycolysis does not require oxygen in order to occur. Explain what this tells us about the evolutionary history of this metabolic process. 2. In the absence of oxygen, fermentation occurs. Explain the primary purpose of this process. 3. Identify the source of the electrons that travel down the electron transport chain. Explain why oxygen is the final electron acceptor in aerobic cellular respiration. 4. Create a graphic organizer that illustrates the reactants and products for each of the major stages of cellular respiration: (a) Glycolysis (b) Krebs Cycle (c) Oxidative phosphorylation 5. Compare and contrast chemiosmosis that takes place in the mitochondria to produce ATP to the osmosis of water that can occur in a cell. 6. Carbohydrates are the primary energy source for many cells, but proteins and lipids can also be used. Describe where these alternative energy sources enter the process of cell respiration.
