The first step of the metabolic process known as glycolysis is the conversion of glucose to glucose- 6-phosphate. This process has a positive value for rG' Glucose + Pi Glucose-6-phosphate + H2O rG' = +13.8 kJ/mol-rxn This reaction is coupled to the hydrolysis of ATP ATP + H2O ADP + Pi rG' = -30.5 kJ/mol-rxn What is the sum of these two equations and the value of rG' for the coupled reaction? Is the coupled reaction product-favored at equilibrium?

TPP is a coenzyme for transketolase, the enzyme that catalyzes the conversion of a ketopentose (xylulose- 5-phosphate) and an aldopentose (ribose-5-phosphate) to an aldotriose (glyceraldehyde-3-phosphate) anda ketoheptose (sedoheptulose-7-phosphate). Notice that the total number of carbons in the reactants and products is the same (5 + 5 = 3 + 7). Propose a mechanism for this reaction.

Wheeler and Mathews (J. Biol. Chem. 287:31218–31222 (2012)) reportedthe NAD+ and NADH concentrations in yeast mitochondria as 20 mM and0.3 mM, respectively. Consider the malate dehydrogenase reaction, which is part of the citric acid cycle:malate + NAD+ → oxaloacetate + NADH + H+ ΔG∘' = +29.7 kJ/molIf malate concentration in yeast mitochondria is 0.4 mM, what is the maximum concentration of oxaloacetate needed to make the reaction exergonic at pH 7.0 and 37°C?
In one of the steps in this pathway fructose 1,6-biphosphate (F1,6BP) is converted to gylceraldehyde-3-phosphate (G-3-p) and dihydroxyacetone phosphate (DHAP). This reaction is catalyzed by the enzyme aldolase. For this reaction at 25 celcuius and Ph7 we have: Keq= 10-4M and Delta G = +5456 cal/mol Calculate the following: The concentration of F1, 6BP, DHAP and G-3-P at equilibrium when the initial F1,6BP is (A) 1M, (b) 10-2 M, (c) 2 X 10*4 M and (d) 10-5 M. I been trying to solve this problem but I dont even know where to begin with. Atleast help me with problem A, I would be able to guide myself through.
For the hydrolysis of glucose-6-phosphate, glucose-6-P + H₂O ⇌ glucose + Pi ∆G'°= -13.8 kJ/mol and K'eq = 3.81×10⁻³ at 25°C. Therefore the [glucose-6-phosphate]/[glucose] ratio is about 1/260 at equilibrium. What is the [glucose-6-phosphate]/[glucose] ratio at equilibrium when this reaction is coupled to ATP hydrolysis in the coupled reaction glucose + ATP ⇌ glucose-6-phosphate + ADP and [ATP] = ADP]? For ATP hydrolysis ∆G'°= -30.5 kJ/mol at 25°C.
In strong base, glucose converts to fructose. Explain howthis conversion occurs.

Anaerobic glycolysis (i.e., lactic acid fermentation) produces pyruvate that is then converted to lactate through the activity of lactate dehydrogenase. The conversion of pyruvate to lactate would seem to be an unnecessary step, since this process does not result in any further release of energy. Explain the necessity for the production of lactate as the endpoint for anaerobic glycolysis.
