Tautomerization of enolpyruvate to pyruvate occurs in step 10 of glycolysis. If DG°’ = -46 kJ/mol, what is the ratio of pyruvate to enolpyruvate at equilibrium? Steady-State Concentrations of Glycolytic Metabolites in Erythrocytes Metabolite mM Glucose 5.0 Glucose-6-phosphate 0.083 Fructose-6-phosphate 0.014 Fructose-1,6-bisphosphate 0.031 Dihydroxyacetone phosphate 0.14 Glyceraldehyde-3-phosphate 0.019 1,3-Bisphosphoglycerate 0.001 3-Phosphoglycerate 0.12 2-Phosphoglycerate 0.030 Phosphoenolpyruvate 0.023 Pyruvate 0.051 Lactate 2.9 ATP 1.85 ADP 0.14 Pi 1.0
One reaction in glucose metabolism involves the cleavage of fructose-1, 6-bisphosphate to dihydroxyacetone phosphate and glvceraldehyde-3-phosphate. Enzymatically the reaction is catalyzed by aldolase. However, it can also be catalyzed by aqueous hydroxide. Propose the mechanism for the base-catalyzed reaction.
I am confused with this glucose structure, Can you answer the
question asked on the right side of the page, please?

3. It is uncommon for one molecule to act as both an activator and inhibitor in metabolism. Which of the following molecules both activates glycolysis and inhibits gluconeogenesis? A. NAD B. Fructose 1,6-bisphosphate C. Pyruvate D. Fructose 2,6-bisphosphate E. Glucose 6-phosphate 4. Regulation of phosphorylase is by phosphorylation. However, this covalent modification increases or decreases activity without completely inhibiting it. The velocity plot is sigmoidal. What statement can be made about this enzyme? A. It likely follows a Michaelis-Menten kinetic....
2)
if a single glucose molecule was completely catabolized to 2
pyruvate, then the liver built the 2 pyruvate back to glucose, how
much free energt would be lost?

Please provide answers and explanation for the below problem,
thanks.
A key step in the metabolism of glucose for energy is the isomerization of glucose-6-phosphate (G6P) to fructose-6 phosphate (F6P) as shown below. G6P F6P At 298 K, the equilibrium constant for the isomerization is 0.510. (a) Calculate ΔG° at 298 K. (b) Calculate ΔG When Q, the [F6P]/[G6P] ratio, equals 20.0. (c) Calculate ΔG When Q = 0.700. (d) Calculate Q in the cell iAG =-2.50 kJ/mol. kJ/mol kJ/mol...
