(1 pt) What determines whether a runner is a sprinter or a distance runner? 2. 3. /64 ÷ 2 = /32 (1 pt) Excelling at one sport or another is determined by a) nature (genetics) b) nurture (training) c.) both d.) neither (1 pt) Explain your answer. Obj. 6-1 Label the diagram of a mitochondrion using the words in the word bank. (19 pts) WORD BANK: 1 pt. each e- carrier (x3) (3 pts) glycolysis Krebs Citric Acid Cycle oxidative phosphorylation inner membrane outer membrane intermembrane space matrix ATP (x3) (3 pts) Oxygen CO2 (x3) (3 pts) (Glucose) (C6H12O6) Pyruvic Acid (C3H6O3) 4. (8 pts) 6.2 Label the following diagram and use it to compare breathing with respiration. Use the following words for labeling. Glucose + O2 CO2 + H2O +ATP Muscle Cells Lungs Breathing CO2 O2 Breathing Cellular Respiration 5. (2 pts) Comparison: 6. (1 pt) 6.3 Write the balanced chemical equation for cellular respiration. 7. 8. (5 pts) Use behaviors and conditions (eat, inhale, exhale (x2), energy level) to label the above equation. (2 pts) 6.4 About how many times more energy does walking require as compared to sitting? Use table 6.4 on page 91 to answer this question. Show your calculations.

PROCESS CELL OR ORGANELLE REGION GLYCOLYSIS CITRIC ACID CYCLE LACTIC ACID FERMENTATION ALCOHOLIC FERMENTATION 10. (2 pts) What provides the driving force for splitting glucose (glycolysis)? 6.13 Compare alcohol and lactic acid fermentation. 11. (1 pt) Does glycolysis still occur when oxygen is not present (anaerobic)? 12. (2 pts) Does glycolysis produce any ATP or high energy e- for the electron transport chain? If so, how many net ATP? 13. (1 pt) Is carbon dioxide gas (CO2) produced during lactic acid fermentation? 14. (2 pts) Is carbon dioxide gas (CO2) formed during alcoholic fermentation? (Hint: can alcohol be “bubbly”? Give an example.) 15. (5 pts) Describe how “oxygen debt” occurs. How do we “repay” our oxygen debt? 16. (1 pt) Define obligate anaerobe (strict anaerobe). 17. (3 pts) Give two examples of facultative anaerobes. What does this mean? 18. (3 pts) 6.14 List three characteristics of glycolysis that indicate that it is an ancient metabolic system. 19. (2 pts) 6.15 Animals store most of their energy reserves as fats, not as polysaccharides. What is the advantage of this mode of storage for a bird that migrates? 20. (1 pt) 6.16 Explain how one can gain weight and store fat even when on a low-fat diet. (Hint: Look for G3P and acetyl CoA in fig. 6.15 and 6.16.)

Fill in the blanks on the table. Process Analogy Hand games e- transport chain Respiratory poisons Garden hose e- transport chain creates the proton gradient Bucket brigade Equivalents 4+2=6 6–1=5 5–1=4 Stepping down the energy gradually instead of leaping from the top and hitting the bottom Bucket = ______ Water = _____ Explanation The sequential breakdown of carbon molecules is simple math. The pull of gravity vs. electronegativity Water must be able to flow just like e- must be accepted by oxygen. If no flow, everything backs up and quits running. The buckets (__) move from the water source to the burning barn and back while the water (___) moves in one direction, to the barn (inner membrane space) and accumulates. (H+, pH) ________= H+ chemiosmosis Hydroelectric dam ______ = inner membrane ________ = ATP Synthase What provides the driving force for the following processes? 21. creating the proton gradient (electron transport chain): 22. producing ATP (chemiosmosis or oxidative phosphorylation): 23. Obj. 6.6 List the cell regions or organelle regions where the processes occur. Use whichever is more specific!
