What is the difference between NAD+/NADH and FAD+/FADH2?

Homework Answers

Answer #1
  • NAD is nicotinamide adenine dinucleotide and FAD is flavin adenine dinucleotide
  • NAD is used as coenzyme whereas FAD is considered as a cofactor used in redox reactions.
  • FAD can accommodate two hydrogens whereas NAD can accept only one hydrogen
  • The reduction of NAD leads to the formation of NADH+ in glycolysis and Kreb's cycle whereas reduction of FAD leads to the formation of FADH2 in Kreb's cycle
  • During electron transport chain, 3 ATPs are produced from a single molecule of NAD whereas only 1.5-2 ATPs are generated from a molecule of FAD

Oxidation NADH and FADH2 are often considered “energy currency” in cellular metabolism because they are generated directly from Glycolysis and the TCA cycle. Using the following half-cell potentials, calculate the Gibbs Free Energy that can be derived from the oxidation of NADH and FADH2. Use the Faraday Constant at 96,500 J/V mol.(should get two values) FAD + 2H+ +2 e- = FADH2 Eo = -0.219V NAD+ + H+ + 2 e- = NADH Eo = -0.320V

Thermodynamic constrains. Compare the delta G' standard values for the oxidation of succinate by NAD+ and by FAD. Use the data given to find E'0 of the NAD+-NADH and fumerate-succinate couples, and assume that E0' for the FAD-FADH2 redox couple is nearly 0.05 V. Why is FAD rather than NAD+ the electron acceptor in the reaction catalyzed by succinate dehydrogenase? Given E0' NAD NADH -0.32 V E0' fumarate - succinate +0.03

In step 6 of the citric acid cycle, succinate + FAD → fumarate + FADH2. Which statements concerning this reaction are true? Refer to the figure shown. (Note that in redox reactions, the molecule that “causes” another to gain or lose electrons is referred to as the agent.) Select all that apply. This is not an oxidation/reduction reaction; that is, no electrons have moved. Fumarate is more oxidized than succinate. FAD is more reduced than FADH2. FAD is an oxidizing...
