Depоlаrizаtiоn оf а nerve cell results in an increase in the amount of [pos] charge on the inside of the membrane. This causes the voltage sensor of the voltage-gated sodium channel to be [out], allowing opening of the sodium channel. Repolarization, with its concentration-dependent efflux of K+, decreases the [p2] charge on the inside of the membrane and causes the voltage sensor be [pulled]. 

Shоrt аnswer questiоn. Yоu must show your work аnd use аppropriate units on all numbers that require them.  1. (26 points) Consider the synthesis of one mole of glucose in a C3 plant in the boreal forest (the band of forest that encircles the planet at about 55 degrees latitude and is one of the primary drivers for the dip in CO2 levels seen each April) where the average daylight summer temperature is about 10°C.  a) (3 pts)How many moles of CO2, NADPH, and ATP are required? b) (9 pts) If the chloroplast ATP synthase has 14 c subunits, what is the total number of photons required for the synthesis of a mole of glucose? You will need to take into account both linear photosynthesis and cyclic electron flow.  c) (6 pts) 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 3.2. For simplicity, assume the membrane potential is 0 volts.  d) (6 pts) The two photosystems take the energy of all light and basically convert it to the equivalent of light with an average wavelength of 690 nm. Based on the number of photons required (remember that we are working with a mole of glucose so your number of photons will be in einsteins), what is the total amount of energy available for glucose synthesis?  e) (2 pts) What percentage of the light energy is captured in the proton gradient? Don't be surprised if the value is rather small since we are looking only at the ATP production and not including the NADPH production.    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.
