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?

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?

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)
