6 3 Insert Question ere A A Keep Phosphorylatin' 300 pts Which of the following is NOT an example of the cellular work accomplished with the free energy derived from the hydrolysis of ATP? mechanical work, such as the beating of cilia chemical work, such as the synthesis of a new protein the production of heat, which raises the temperature of the cell transport work, such as the active transport of a molecule into a cell / : the production of heat, which raises the temperature of the cell Link to image

7 Keep Phosphorylatin' 400 pts 4 Insert Question ere Most of the electron carriers (NA and A 2 ) that deliver electrons to the electron transport chain in mitochondria come from which of A the following? A glycolysis the citric acid cycle oxidative phosphorylation substrate level phosphorylation / : the citric acid cycle

8 Keep Phosphorylatin' 500 pts 5 Insert Question ere In the overall process of glycolysis and cellular respiration, A is oxidized and is reduced. A ATP... oxygen glucose... ATP glucose... oxygen carbon dioxide... water / : glucose... oxygen

9 1 Insert Question ere A A Take My reath Away 100 pts uring aerobic respiration, molecular oxygen (O 2 ) is used for which of the following purposes? at the end of glycolysis to oxidize pyruvate as a source of O 2 in every reaction that produces O 2 at the end of the citric acid cycle to regenerate citric acid at the end of the electron transport chain to accept electrons and form 2O / : at the end of the electron transport chain to accept electrons and form 2 O

10 2 Insert Question ere A Take My reath Away 200 pts In an experiment, mice were fed glucose ( 6 12 O 6 ) containing a small amount of radioactive carbon (carbon 14). The mice were closely monitored, and in a few minutes radioactive carbon atoms showed up in which compound? A ATP water oxygen gas carbon dioxide / : carbon dioxide

11 3 Insert Question ere Take My reath Away 300 pts If muscle cells in the human body consume O 2 faster than it can be supplied, the cells will not be able to carry out oxidative phosphorylation and switch to A fermentation. ermentation is essentially glycolysis plus an extra step in which pyruvate is reduced by electrons from NA to form lactate or alcohol and carbon dioxide. This last step A enables the cell to recycle NA +. prevents pyruvate from accumulating. extracts a bit more energy from glucose. enables the cell to make pyruvate into substances it can use. A / : enables the cell to recycle NA +.

12 Take My reath Away 400 pts 4 Insert Question ere ow many molecules of ATP are gained by substrate level phosphorylation from the complete breakdown of a single molecule of A glucose in the presence of oxygen? A / : 4 (2 from glycolysis + 2 from citric acid cycle)

13 5 Insert Question ere A A Take My reath Away 500 pts A chemist has discovered a drug that blocks phosphoglucoisomerase, an enzyme that catalyzes the second reaction in glycolysis. e wants to use the drug to kill bacteria in people with infections. This is a bad idea because glycolysis can occur without the action of enzymes. glycolysis produces so little ATP that the drug will have little effect. bacteria are prokaryotes; they usually don't need to perform glycolysis. human cells must also perform glycolysis; the drug might also kill humans. / : human cells must also perform glycolysis; the drug might also kill humans.

14 1 Insert Question ere A What Stomata With You? 100 pts In both plants and animals, most of the ATP for synthesis of proteins, cytoplasmic streaming, and other cellular activities comes directly from the process of chemiosmosis and A the alvin cycle. oxidative phosphorylation. cyclic photophosphorylation. noncyclic photophosphorylation. / : oxidative phosphorylation. Study this diagram! (igure 10.17)

15 2 Insert Question ere A What Stomata With You? 200 pts elow is an absorption spectrum for an unknown pigment molecule. What color would this pigment appear to you? A violet blue green orange / : blue (the color that is least absorbed)

16 3 Insert Question ere AM plants differ from 3 and 4 plants in that AM plants A What Stomata With You? 300 pts A open their stomata only at night. initially fix carbon using PP carboxylase. are better adapted to cold, damp conditions. keep their stomata only partially open during the day. A / : open their stomata only at night.

17 4 Insert Question ere A What Stomata With You? 400 pts Assume a thylakoid is somehow punctured so that the interior of the thylakoid is no longer separated from the stroma. This damage will have the most direct effect on which of the following processes of the light reactions? A the synthesis of ATP the splitting of water the reduction of NAP + the flow of electrons from photosystem II to photosystem I A / : the synthesis of ATP

18 What Stomata With You? 500 pts 5 Insert Question ere Which of the following processes could still occur in a chloroplast in the presence of an inhibitor that prevents A + from passing through ATP synthase complexes? A the alvin cycle noncyclic (linear) photophosphorylation oxidation of NAP in the stroma generation of a "proton pressure" in the thylakoid space / : generation of a "proton pressure" in the thylakoid space

19 1 Insert Question ere Plant xperiments 100 pts In an experiment studying photosynthesis performed during the day, you provide a plant with radioactive carbon ( 14 ) dioxide as a metabolic tracer. The A 14 is incorporated first into oxaloacetic acid (oxaloacetate). The plant is best characterized as a A 4 plant. 3 plant. AM plant. chemoautotroph. A / : 4 plant.

20 2 Insert Question ere Plant xperiments 200 pts Imagine you had a tiny p probe that could measure the p inside a living plant cell. What portion of an illuminated 3 plant cell would you A expect to have the lowest p? A cytoplasm chloroplasts thylakoid spaces stroma of chloroplasts / : thylakoid spaces

21 3 Insert Question ere Plant xperiments 300 pts Some photosynthetic organisms contain chloroplasts that lack photosystem II, yet are able to survive. The best way to detect the lack A of photosystem II in these organisms would be A to test for O 2 fixation in the dark. to test for production of O 2 in the light. to test for production of either sucrose or starch. to do experiments to generate an action spectrum. / : to test for production of O 2 in the light.

22 4 Insert Question ere Plant xperiments 400 pts Soybeans have been genetically modified so that they resist the effect of the herbicide glyphosate. This allows the soybeans to be cultivated A without competition. The graph shows the percent of dead cells in samples of wild type and genetically modified soybean leaves at regular intervals after exposure to glyphosate. The values in the graph represent the sample mean ±2 SM of three simultaneously conducted experiments. At what time (in hours) did the results of this investigation begin to show a statistically significant difference? / : 48 hours (error bars do not overlap) A 0 hours 24 hours 48 hours 72 hours

23 5 Insert Question ere Plant xperiments 500 pts Scientists performed an experiment with isolated chloroplasts. The chloroplasts were first made acidic by soaking them in a solution at p 4. After the thylakoid space reached A p 4, the chloroplasts were transferred to a basic solution at p 8. The chloroplasts are then placed in the dark. Which of these compounds would you expect to be produced? A ATP 3P NAP ATP and NAP A / : ATP ( + ions flow down the gradient through ATP synthase)
