QUESTION 8 ethanol and why? Propionato O,1,4870 3254 Ehanel o,1,308.0 26.32 Aoetate o Formate O, -847.0 18.72 -234.0 4.90 NO, -1,282.0 2020 NO,1,2670 24.00 None -14.6 3.50 o a the catabolism of ethanol without an oxidant because the JGis almost positive o b None-ethanol can only be catabolized syntrophically the o dation of ethanol with Oygen because the G s the largest negatve number indicating the large yield of energy released o d. The oxidation of ethanol yields too little biomass to be catabolized o e the oxidation of ethanol with NO as the oxidant is because of the large yield of energy released

Explanation / Answer

Answer. : C. Oxidation of ethanol with oxygen because the delta G is the largest negative number indicating the large yield of energy released.

The table shows 3 different ways of ethanol catabolism ( with oxygen, with NO3- and without and oxidant). Of these 3, the larger amount of energy is obtained when oxidation occurs in the presence of oxygen. Also the amount of biomass produced by this method is the largest among the 3.
