WebThe standard reduction potential (Eº') for the isocitrate dehydrogenase reaction in the citrate cycle is -0.38 Volts as shown on the front of the exam. What is the actual reduction potential (E) of this reaction at 37ºC when the ratio of e- acceptor to e- donor is 10? E = Eº' + RT/nF ln (e-acceptor)/ (e- donor) E = Eº' + RT/nF ln (10)/ (1) WebE °' = 0.816 V It is no coincidence that oxygen has a very high E °' and that we require it for life. Oxygen’s great affinity for electrons allows it to be used in living organisms as an electron “sink” or dumping ground for excess electrons …

WebWhen two reactions are coupled, they can be added together to give an overall reaction, and the Δ G of this reaction will be the sum of the Δ G values of the individual reactions. As long as the overall Δ G is negative, both reactions can take place. http://colormine.org/delta-e-calculator
