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:
