Standard redox potential of half-reactions fumerate+2h +2esuccinate e = 0.030v, nad2h +2e- nadh +h+ e = -0.32v fad+2h+2e-fadh2 e= 0.09v succinate dehydrogenase in tca cycle uses fad as coenzyme and also is complex ii of etc. (9 pts) 1. (a) calculate ag of the reaction below. succinate+fad-fumerate + fadh, (b) calculate the same reaction if succinate dehydrogenase uses nad+ as coenzyme. succinate+nad+- fumerate+nadh+ h (c) how does using nad+ as coenzyme affect overall electron flux in etc?
ag°= -nfae°, f = 96485 j/mole. v formula you might need:

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
