Write a balanced reaction describing the biological oxidation of organic matter (use a formula for the organic matter of CH2O) to carbon dioxide by denitrifying bacteria (use nitrate reduction to nitrogen gas as the electron accepting process).  How many grams of nitrate are needed for the complete oxidation of 1 gram of organic matter according to your balanced reaction above?

Identify the chemical basis for ApH and AY across the chloroplast thylakoid membrane by dragging the descriptions to their targets. Be sure to notice that the upper arrow iindicates ApH and the lower arrow indicates ΔΨ.

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.
