Concept explainers
The water in the Yellowstone National Park hot springs shown here is around 160°F (70°C). Biologists assumed that no species of organismscould live in water above about 130°F(55*C), so thev were surprised to find several species of bacteria there, now called thermophiles
15. SYNTHESIZE YOUR KNOWLEDGE |
("heat-lovers"). You've learned in this chapter how an enzyme from one species, Thermus aquaticus, made feasible one of the most important DNA-based techniques used in labs today. ldentify the enzyme, and indicate the value of its being isolated from a thermophile. Suggest other reasons why enzymes from this bacterium (or other therrnophiles) might also be valuable.

- Pollutants such as halogenated aromatic hydrocarbons (HAHs)are usually spotty in their distributions in bodies of water. Thuseven if HAHs are present, fish might be able to avoid beingexposed to them. Suppose you want to determine if the fishliving in an industrialized harbor are in fact more exposed toHAHs than fish in a more pristine harbor. Why might a study ofliver P450 enzymes be particularly useful for your purposes?arrow_forwardKnowing that for a bacterial colony to be able to grow it must produce product "3" AND "4", use the information in the image to describe which enzyme(s) are that are Non-Functional in Colony C? Please note error in enzyme description at bottom of image. X converts 1 into 2; Y converts 1 into 3; and z converts 2 into 4.arrow_forwarda. Name a metabolic type that might be found in Section 3 of the column. List the energy source and the compounds the organism would use as carbon and electron sources. b. You isolated a bacterium from Section 2 of the column. You hypothesize that this bacterium might ferment xylem, a common carbon source found in plants. What carbohydrate test would you use to test your hypothesis? Be specific about any compound(s) that would need to be in the test. If the bacterium could ferment xylem, what result would you expect?arrow_forward
- in cells, an enzyme catalyzes the reaction ab → a + b. it was isolated, however, as an enzyme that carries out the opposite reaction a + b → ab. explain the paradox.arrow_forwardAn organism that can synthesize all its required organic componentsfrom CO2 using energy from the sun is aa. photoautotroph b. photoheterotroph c. chemoautotroph d. chemoheterotropharrow_forwardSome bacteria are metabolically active in hot springs because(A) they are able to maintain a lower internal temperature.(B) high temperatures make catalysis unnecessary.(C) their enzymes have high optimal temperatures.(D) their enzymes are completely insensitive to temperature.arrow_forward
- Enzymatic activity is rapidly destroyed at physiologically high temperatures. How do you reconcile this observation with the existence of bacteria and algae that grow in hot springs where the temperature may be as high as 73 °C?arrow_forwardWhich of the following pathways requires molecular oxygen (O2)? a. aerobic respiration b. lactate formation c. alcoholic fermentation d. photosynthesisarrow_forwardOrganisms ATP NADH NADPH FADH2 Ethanol 1 20 100 0 0 50 2 350 400 0 100 1 3 500 410 200 100 1 Three organisms were tested biochemically for their production of energy, and various compounds were measured in each organism.

- Human enzymes have an optimal temperature of approximately 37°C, while thermophilic bacterial enzymes have an optimal temperature of approximately 75°C. Which of the following statements best explains the change in the rate of these enzymatic reactions between 40°C and 70°C? The rate of reaction of the human enzyme decreases as the reaction requires less energy to proceed, while the rate of the reaction of the thermophilic bacterial enzyme increases as the reaction requires more energy to proceed. The rate of reaction of the human enzyme decreases as the enzyme denatures, while the rate of the reaction of the thermophilic bacterial enzyme increases as molecules move faster, causing more collisions between the enzyme and substrate. The rate of reaction of the human enzyme decreases as the entire enzyme denatures, while the rate of the reaction of the thermophilic bacterial enzyme increases as only the active site of the enzyme denatures at higher temperatures, allowing for a tighter…arrow_forwardThe fact that energy transformations increase the amount of entropyis the basis of which of the following?a. cell theoryb. first law of thermodynamicsc. second law of thermodynamicsd. oxidation-reduction reactionsarrow_forwardSCIENTIFIC INQUIRY • DRAW IT A researcher has developedan assay to measure the activity of an important enzymepresent in pancreatic cells growing in culture. She adds theenzyme’s substrate to a dish of cells and then measures theappearance of reaction products. The results are graphed as theamount of product on the y-axis versus time on the x-axis. Theresearcher notes four sections of the graph. For a short periodof time, no products appear (section A). Then (section B) thereaction rate is quite high (the slope of the line is steep). Next,the reaction gradually slows down (section C). Finally, thegraph line becomes flat (section D). Draw and label the graph,and propose a model to explain the molecular events occurringat each stage of this reaction profile.arrow_forward
