29. When fructose-6-PO$_4$ is externally available to the organism, when the species is using anaerobic chemolithotrophy as its metabolism, it will • Use the fructose-6-PO$_4$ as a carbon source • Use the fructose-6-PO$_4$ as an electron donor • Use the fructose-6-PO$_4$ in glycolysis • Ignore the fructose-6-PO$_4$ in its environment

Step 1
In anaerobic chemolithotrophy, the organism obtains energy by oxidizing inorganic compounds, such as hydrogen sulfide or ammonia, instead of using oxygen as the final electron acceptor. Fructose-6-PO4 is a phosphorylated sugar molecule and is an intermediate Show more…

Fructose-6-phosphate is phosphorylated to fructose-(1-6)-bisphosphate as part of the glycolytic pathway. The phosphorylation of fructose-6-phosphate by phosphate is described by the following equation: Fructose-6-phosphate + Pi ↔ Fructose-(1-6)-bisphosphate ΔG0' = +47.7 kJ/mol Suppose that the phosphorylation of fructose-6-phosphate is coupled to the hydrolysis of ATP (-30.5 kJ/mol). What is the ΔG0' for the coupled reaction?

Fructose 6-phosphate + Pi ↔ fructose 1,6-bisphosphate + H2O ΔG'º = +4.3 kcal/mol ATP + H2O ↔ ADP + Pi ΔG'º = -7.3 kcal/mol Write the balanced formula for a new reaction that would couple the top reaction to the hydrolysis of ATP in such a way that the formation of fructose 1,6-bisphosphate will be thermodynamically favorable. Include the new value for ΔG'º.
