Most biochemists agree that the most accurate number of H+ needed to generate one ASP is blank. Therefore one NADH generated about blank ATP molecules?

The coenzymes NAD+ and NADP+ are important electron carriers that pick up electrons from one pathway and deliver them to another. Below is a list of pathways or enzyme complexes that we have covered in class.  Indicate which coenzyme these pathways or complexes produce by writing NAD+, NADP+, NADH or NADPH in the blank provided.    ________ glycolysis ________ citric acid cycle ________ alcoholic fermentation ________ pyruvate dehydrogenase complex ________ gluconeogenesis ________ mitochondrial electron transport ________ photosynthesis light reactions ________ photosynthesis dark reactions

The reduction potentials of iron in each of the cytochromes in the electron transport complexesvary from 0.The reduction potentials of iron in each of the cytochromes in the electron transport complexes vary from 0.1 V to 0.39 V. Explain why these different values are necessary for the operation of this process

Calculate the standard free-energy change, deltaG'o, for the reaction in which acetaldehyde is reduced by the biological electron carrier NADH in the reaction acetaldehyde + NADH + H+ → ethanol + NAD+. Then calculate the actual free-energy change, deltaG, when the acetaldehyde is 1.51 M, the NADH is 1.02 M, the ethanol is 0.13 M and the NAD+ is 0.19 M, at 33.35oC and pH = 7. Give the actual free-energy change in kJ/mol to one decimal place. See Table 13-7b for the E'o values. please provide comprehensive explaination with each step.
