When the following reaction reached equilibrium the concentration of glucose 1-phosphate is 34mM, and the concentration of glucose 6-phosphate is 190mM. At standard temperatures and pressure, calculate the Keq and the ΔGo' glucose 6-phosphate <---(phosphoglucoisomerase)---> glucose 1-phosphate Keq= ΔGo' =
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.
first explain what endergonic and exergonic reactions are in your words,now relate both the reactions with biosynthetic and biodegraditve pathways example.
An 90 kg subject consumed a snack that contained 80 g of carbohydrate. Before eating the snack the subject’s blood glucose was 6.0 mmol.L-1. Calculate the concentration of glucose (mM) that would be reached in the blood after consuming the snack.Assume that all the carbohydrate in the snack was converted to glucose, rapidly absorbed and distributed throughout the extracellular water (ECW) within 30 minutes. Assume ECW is approximately 20% of body weight and the glucose is not metabolised further.
1. Discuss the steps involved in glycolysis.
can you add more details becuase I need more for the 4 of them add more step by step explanttion
Lactate dehydrogenase catalyzes the following equilibrium reaction in both liver and muscle cells: pyruvate+NADH+H+lactate+NAD+ In terms of equilibrium, explain why lactate must be removed from muscle cells under anaerobic conditions and why lactate does not accumulate in the liver under these conditions. Hint: Think of the Cori cycle.
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?
If the hydrolysis of 1 M glucose 6-phosphate catalyzed by glucose 6-phosphatase has a delta G’^o of -11.386 kJ/mol at 25 °C, what percentage of substrate remains once the reaction reaches equilibrium assuming no product was initially present? (Round answer to the nearest whole number) (R = 8.315 J/mol · K)
Many metabolites are maintained at steady‑state concentrations that are far from equilibrium. A comparison of ?′eq and ? , the mass‑action ratio, can determine whether a metabolic reaction is far from equilibrium...
If the following two reactions were coupled, what would be the delta G for the overall exergonic reaction? Only put the numeric answer in (not units) into the blank and also be sure to include "-" sign in front of the number if the answer is negative. ATP + H2O --> ADP + Pi delta G = -31 kJ/molGlucose + Pi --> glucose-1-phosphate + H2O delta G = 21 kJ/mol
