Write a complete reaction,using half reactions, for oxidation of Iron(II)with nitrate as the electron acceptor.
4. Consider the metabolism of glucose by microorganisms using nitrate (NO3-) as an electron acceptor and by microorganisms using sulfate (SO2-) as an electron acceptor. Redox pair CO/C6H1206 -0.43 NO,-/N +0.74 SO 2-/HS E, V -0.22 a. Write out the balanced reactions in each case, starting with the redox pairs and fol-
Answer
Write balanced half-reactions for the following redox reaction: reduction: 0 oxidation:
Write balanced half-reactions for the following redox reaction: reduction: 0 oxidation:
Some bacteria can use nitrate as an electron acceptor instead of oxygen, reducing it to nitrite. This requires an enzyme called nitrate reductase. Write a balanced equation for the oxidation of NADH by nitrate. Calculate the Gibbs free energy change under standard state conditions (ΔGo’) for the oxidation of NADH by nitrate [tip: you will need to look at Table 3.5 in the textbook]. The Faraday Constant, F, is 96.5 kJ/V.mol.
