Question

Imagine that one mol of a monosaccharide was completely combusted to water and carbon dioxide and the free energy liberated from this process (ΔG°'= -688 kcal/mol) was converted with 100% efficiency to the synthesis of a three-carbon, bisphosphorylated metabolite (i.e., phosphorylated at two different carbons rather than successive phosphorylations "in a row" as seen with ADP and ATP). How many mol of the three-carbon, bisphosphorylated metabolite could be made in this manner if the standard free energy of hydrolysis for the above metabolite was -11 kcal/mol? Report your answer to the nearest ones.

Answer 1

One mol of a monosaccharide was completely combusted to water and carbon dioxide.

The free energy liberated from this process is kcal/mol .....(1)

The standard free energy of hydrolysis for the above metabolite was -11 kcal/mol...(2)

Divide (1) with (2) to obtain the number of moles of the three-carbon, bisphosphorylated metabolite could be made

The answer to the nearest ones is 60.
