Answer #1

It will be zero according to condition 1, 2, 3and 5.

1. the enzyme hexokinase is involved in this reaction of conversion of glucose to G6P and is necessary so without it forward reaction does not take place.

2. If glucose, the substrate which is to be converted, concentration is 0 then no forward reaction is possible.

3. the direction of conversion in the cell is dependent on the relative concentration of allosteric regulators which exert kinetic control over the enzymes by acting on them in opposing pathways.

5. if ATP, Glucose and hexokinase is present forward reaction takes place if allosteric factors allow.

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...
