In which of the following metabolic conversions is ATP “generated” during glycolysis? Glucose —> Glucose-6-phosphate 1,3-Bisphosphoglycerate —> 3-Phosphoglycerate Fructose-1,6-bisphosphate —> Dihydroxyacetone phosphate + Glyceraldehyde-3-phosphate Glucose-6-phosphate —> Fructose-6-phosphate 2-Phosphoglycerate —> 3-Phosphoglycerate
Specify the number of carbon atoms present and the number of phosphate groups present in each of the following glycolysis intermediates (3 points each) 1. Glucose 6 phosphate 2. Fructose 1, 6, phosphate 3. Glyceraldehyde 3-phosphate 4. 3-phospholglycerate 5. Fructose 6 phosphate
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]; [P;] = 1 mM. Consider the glycolytic reaction catalyzed by hexokinase: ATP + glucose ADP + glucose-6-phosphate AG = - 16.7 kJ/mol (a) Calculate the equilibrium constant (K) for this reaction at 298°K, and from that, calculate the maximum [glucose-6-phosphate]/ Iglucose] ratio that would exist under conditions where the reaction is still thermodynamically favorable. (b) Reversal of this interconversion in gluconeogenesis is catalyzed by glucose-6-phosphatase: glucose-6-phosphate + H20 = glucose + P AG" = -13.8 kJ/mol
