16. What is the net energetic cost of converting two pyruvate to one glucose by gluconeogenesis in ATP equivalents?

a. 2

b. 4

c. 6

d. 8

17. Why doesn’t hexokinase catalyze the final step of gluconeogenesis as

glucose-6-phosphate + ADP à glucose + ATP ?

a. DG°¢ for this reaction is very negative, and thus unfavorable.

b. DG°¢ for this reaction is very positive, and thus unfavorable.

c. Since ATP inhibits hexokinase, it wouldn't be efficient.

d. What are you talking about? That's exactly what does happen.

The glucose/glucose-6-phosphate substrate cycle involves distinct reactions of glycolysis and gluconeogenesis that interconvert these two metabolites. Assume that under physiological conditions, [ATP]=[ADP] and [Pi]=1mM. Consider the following glycolytic reaction catalyzed by hexokinase: ATP+glucose⇌ADP+glucose−6−phosphateΔG∘′=−16.7kJ/mol Calculate the equilibrium constant (K) for this reaction at 298 K, From the equilibrium constant, calculate the maximum [glucose-6-phosphate]/[glucose] ratio that would exist under conditions where the reaction is still thermodynamically favorable. The reverse of this interconversion in gluconeogenesis is catalyzed by glucose-6-phosphatase: glucose−6−phosphate+H2O⇌glucose+PiΔG∘′=−13.8kJ/mol K= 262 for...
