-1-BIOS 100 - Summer, 2008 Name:Exam I, 18 July, 2008Michael Muller, Instructor TA:This exam consists of 52 questions lovingly spread over 8 pages. Please check to see that all the pagesare present before you begin. Use a #2 pencil and bubble in all answers. There is a copy of the codonchart located at the end of the test. If you don’t know what to do with that, you’re in a heap of trouble.Your score will be posted on the UIC Blackboard site as soon as they are in. Good Luck! The cell to the right contains glucose facilitatedtransport carrier proteins which can be activated anddeactivated (i.e. they can allow glucose to flow downits concentration gradient or shut off so that noglucose can enter or leave the cell). Use thisinformation plus the information provided in thediagrams to answer questions 1 - 4.1. If the glucose facilitated transport carrier proteins are turned off, what will happen to the cell?A. Water will flow into the cellB. Water will flow out of the cellC. There will be no net movement of water2. If the glucose facilitated transport carrier proteins are turned on, what will happen to theglucose?A. Glucose will flow into the cellB. Glucose will flow out of the cellC. There will be no net movement of glucoseD. We cannot answer this because the direction of glucose movement is dependent uponthe direction of water movement3. If the cell had come to osmotic equilibrium before the glucose facilitated transport carrierproteins were turned on, what will happen to the flow of water?A. Water will flow into the cellB. Water will flow out of the cellC. There will be no net flow of waterD. We cannot answer this because we will need to know the final concentrations ofglucose inside and outside the cell4. Entry of glucose into the cell by the glucose facilitated transport carrier proteins requires ATPenergy?A. Yes, it does. That’s my final answer.B. No, it doesn’t. Did you think I’d fall for that? No deal.C. We don’t know enough about the system to answer this question. Stop trying to trickme, Mike5. How do plant leaves defy gravity and stick out?A. The bark supports the leaves B. Fibers and sclerids support the leavesC. Turgor pressure D. An internal “skeleton” of cellulose and ligninE. None of the above-2-6. Which of the following statements (A-D) about the Na+/K+ pump is FALSE. If statementsA-D are true, then choose E.A. The Na+/K+ pump found in many cells in humans B. The Na+/K+ pump is an example of active transport system which involves an activetransport carrier protein and a facilitated diffusion transport protein workingtogetherC. The Na+/K+ pump transports three Na+ out of the cell and two K+ into the cellD. The Na+/K+ pump is an example of an integral proteinE. All of the above statements about the Na+/K+ pump are TRUE7. Which of the following statements (A-D) about osmosis is FALSE? If statements A-D aretrue, then choose EA. Osmosis produces a physical forceB. A cell placed in a hypotonic solution will expand and possibly burstC. An osmotically active solute can cross a semi-permeable membrane if the appropriatecarrier protein is present.D. Osmosis always occurs from a hypotonic solution to a hypertonic solutionE. All of the above statements about osmosis are TRUE8. How can the facilitated diffusion carrier protein in the H /Sucrose transport system carry+sucrose against its concentration gradient?A. It can’t, it is a facilitated diffusion carrier protein and, therefore, must follow the rulesof diffusionB. It utilizes ATP energy to pump sucrose against the gradientC. It is a symport so if the total gradient of the H+ and sucrose is greater outside thaninside the cell, sucrose can be carried against its gradient.D. None of the above9. I want to grow some plants in a growth chamber located in my closet. Which light bulbwould be best for growing these plants?A. An ultraviolet bulb (350 nm) B. A blue bulb (450 nm)C. A green bulb (550 nm) D. A red bulb (650 nm) 10. If I couldn’t find my first choice (i.e. the answer to #9), this color bulb would be my nextbest choice.A. An ultraviolet bulb (350 nm) B. A blue bulb (450 nm)C. A green bulb (550 nm) D. A red bulb (650 nm) 11. What is the function of NADPH and NADH?A. They are a direct source of energy that acts like ATP - they can phosphorylatemolecules and cause their bonds to weaken and be more easily brokenB. They can serve as nucleotide substitutes when Adenosine is not presentC. They are strong oxidizersD. They are electron carriers - they are mobile throughout the cell and they can reduceother moleculesE. None of the above-3-Matching - Use the key below to select the best answers for questions 12 - 19. I. Glycolysis VI. Lactic Acid FermentationII. Oxidation of Pyruvate VII.
