If yоu wаnted tо set up аn enrichment culture tо find species of oil-degrаding bacteria from water samples of a nearby lake, which of these two media (TSA, or GSA) would be more appropriate to use, and what ingredient in it would you have to replace with oil in order for your enrichment culture to work? Please explain.

Shоrt аnswer: reаd questiоns cаrefully! Prоtons and photons look very similar! You must show your work for full credit. All numbers must have units. 1. (29 points) Consider the synthesis of sucrose in sugarcane, a C4 plant that grows in the tropics where currently, the average daytime temperature is about 28ºC. Sucrose is made from one molecule each of glucose-6-phosphate and fructose-6-phosphate (both intermediates in the production of glucose) via a reaction that requires one equivalent of ATP. For all protons and photons, round up to the nearest whole number. a. (5pts) How many moles of CO2 must be fixed for the net production of a mole of sucrose? How many moles of NADPH and ATP are required for this process? It might be a good idea to state the ratio of CO2:NADPH:ATP that you are using and show any deviations from this ratio. b. (2pts) If all ATP and ATP equivalents were produced by a chloroplast ATP synthase with 14 c subunits, how many moles of protons would be required by ATP synthase? c. (3pts) How many moles of photons are required to produce the NADPH that is required? d. (2pts) How many moles of protons can be pumped in conjunction with the production of the NADPH? e. (5pts) Is this number of protons sufficient to produce the required ATP? If yes, how many extra ATP are made above what is needed for sucrose synthesis? If not, explain how sufficient amounts of ATP can be produced including the number of photons that would be needed for the process. f (6pts) Determine the amount of energy that is used in the production of sucrose based on the ATP and NADPH required. First, using the number of protons pumped to produce the required ATP, determine the amount of energy required for proton pumping if the ∆pH across the thylakoid membrane is 2.9. For simplicity, assume the membrane potential is 0 volts. Second, based on a potential of -1.14 v for the oxidation of water by NADP+, determine the amount of energy captured as NADPH. g. (4pts) Using the energy of sunlight's average wavelength, 550 nm, and the total number of photons you have calculated, how much energy is required for the production of sucrose? Make sure you are using moles, not individual molecules. h. (2pts) Based on your answers to parts f and g, what percentage of energy from sunlight is captured in the proton gradient and NADPH used to produce sucrose? Immediately before submitting your quiz, you must show your answers to the camera for documentation. What you show to the camera must match exactly with what you submit for grading. Hold your paper about 12 inches from the camera and slowly move your paper to capture the entire page. If you have multiple pages, make sure to show all pages in the proper order. Please only show your work and answers for the short answer questions, do not show any scratch work for the multiple choice section. If you do not show your short answer work to the camera as the last thing you do prior to submitting the quiz, you will not receive credit for your short answer work. Submit your short answer portion within 10 minutes of your quiz submission.
