<p>Assessment Questions</p><p>1. Calculate the respiration rate of the 4 different vials with peas. Your answers should be given in ml/min. a. Germinating peas at room temp.</p><p> b. Dried peas at room temp.</p><p> c. Germinating peas in ice bath</p><p> d. Dried peas in ice bath</p><p>2. Which of the two pea types, germinating or non-germinating consumes the most oxygen? Why (what is happening in their cells?)</p><p>3. What is the effect of temperature on pea respiration? Give numerical support for your answer. Why (Hint: How is enzymatic activity affected by temperature)?</p><p>4. If the same experiment was done, but your lab teammate forgot to add the KOH, what would happen? Explain. 5. During aerobic respiration, glucose is broken down to form several end products. Which end products contain the carbon atoms from glucose? The hydrogen atoms from glucose? The oxygen atoms from glucose? The energy stored in the glucose molecules?</p><p>6. What is fermentation? What are the two types of fermentation? What organisms use each type of fermentation?</p><p>7. Draw a Venn diagram showing how respiration and fermentation are similar and how they are different. 8. What are the three pathways involved in the complete breakdown of glucose to carbon dioxide and water? What reaction is needed to join two of these pathways? What are the substrates and products of this reaction and where does it take place?</p><p>9. Write the letter of the pathway that best fits each of the following processes. Pathway a. glycolysis b. Kreb’s cycle c. Electron Transport Chain</p><p>Process 1. Carbon dioxide is given off ______2. Water is formed ______, ______3. NADH becomes NAD+ ______4. Oxidative phosporylation ______5. Cytochrome carriers ______6. Pyruvate ______7. FAD becomes FADH2</p><p>10. Fill in the blanks in the chart to account for the energy yield of each of the steps of cellular respiration.</p><p>Coversion to Acetyl Glycolysis Kreb's Cycle ETC CoA # ATP generated via substrate level phosphorylation</p><p># NADH generated</p><p># FADH2 generated</p><p># ATP generated via oxidative phosphorylation</p><p>Total #ATP generated per glucose = ______11. Explain the mechanisms of substrate level phosphorylation vs. oxidative phosphorylation.</p><p>12. You have just performed an activity using plant seeds. Prepare a system that tests the affect of activity level on respiration rate in a small animal. In the space provided below draw what that system would look like. Make sure that your experiment would be controlled and measurable. Label the parts of your set up.</p><p>13. Your teacher has the flu and the only available substitute knows nothing about cellular respiration. You are given the responsibility to provide the substitute teacher with the important background information needed to explain this topic to the next class. Write a letter below, explaining cellular respiration to the substitute teacher. Make sure to start out with a sentence that explains the “big picture”.</p>
