Please provide an explanation for how to work through this practice problem: Using table 12.1, calculate the free energy change for the synthesis of ATP from cAMP and inorganic phosphate. (Note: cAMP is hydolyzed to AMP, and the free engery of hydrolysis for ATP and ADP is approximately equal.) Table 12.1: (Compound: Change in Free Energy in kJ/mol) cAMP: -50.4 Creatine phosphate: -43.3 ATP: -30.5 Glucose 6-phosphate: -13.9 AMP: -9.2
is this stement false? Intracellular concentrations in resting muscle are as follows: Fructose-6-phosphate (1.0 mM)Fructose-(1-6)-bisphosphate (10.0 mM)AMP (0.1 mM)ADP (0.5 mM)ATP (5.0 mM)Pi (10.0 mM)Under the above conditions the Phosphofructokinase reaction in muscle is more exergonic than under standard conditions.
1 a) What is meant by the ATP currency exchange ratio? Why does the oxidation of mitochondrial FADH2 generate one less ATP than oxidation of mitochondrial NADH? b) If 12 H+ are moved across the inner mitochondrial membrane by NADH oxidation, and each ATP synthesized requires 3 H+ to move through ATP synthase, why are only 3 ATP molecules produced by oxidation of each NADH?
The oxidation of glucose to CO2 and water is a major source of energy in aerobic organisms. It is a reaction favored mainly by a large negative enthalpy change. C6H12O6(s) + 6O2(g) →6CO2(g) + 6H2O(l) ∆H° = -2816 kJ/mol ∆S ° = +181 J/mol . K (a) At 37 °C, what is the value for ∆G°? (b) In the overall reaction of aerobic metabolism of glucose, 32 moles of ATP are produced from ADP for every mole of glucose oxidized. Calculate the standard state free energy change for the overall reaction when glucose oxidation is coupled to the formation of ATP at 37 °C. (c) What is the efficiency of the process in terms of the percentage of the available free energy change captured in ATP?
1 = 2, for sufficiently large values of 1. The energetic equivalent of two molecules of ATP is used to activate an amino acid, yet only one molecule of ATP is used. Explain
1. a. In active muscle cells, the pO2 is about 10 torr at the cell surface and 1 torr at the mitochondria(the organelles where oxidative metabolism occurs). Calculate the percentage of bound oxygentransported to the mitochondria of muscle cells by myoglobin (KD = 2 torr). b. A new oxygen transport protein that exhibits cooperative binding has been isolated and is beingstudied in the lab. Calculate the KD value if Y = 0.76 when pO2 = 18 torr (assume n = 2.5). Howdoes this compare to the KD value for hemoglobin? Does this protein bind more or less tightly tooxygen compared to hemoglobin?
Explain the difference between ΔG°’ and ΔG and calculate the free energy (delta G) of hydrolysis of ATP in a rat liver cell in which the ATP, ADP, and Pi concentrations are 3.4, 1.3, and 4.8 mM.
2.For question number 1 if a mixture was prepared containing 1 M Glucose 6-Phosphate and 0.001 M Glucose 1-Phosphate the ∆G for this reaction is: included question 1 however, need help with 2 and provided the option for the answer 1.What is the Keq for the conversion of Glucose 1-Phosphate to Glucose 6-Phosphate if the phosphate transfer potential for Glucose 1-Phosphate and Glucose 6-Phosphate are 20.9 kJ/mol and 13.8 kJ/mol respectively?
1. Assuming that everything that’s needed to make tripalmitin comes from glucose, how many glucose would be used by adipose tissue in the synthesis of 1 mol tripalmitin? 2. How many ATP would be used (net of produced and used)? 3. If an animal absorbs 35 g glucose (MW = 180 g/mol) from drinking a can of pop, how many grams of tripalmitin (MW = 807 g/mol) can be produced from it in adipose tissue? Please provide only typed answer solution no handwritten solution needed allowed
The standard free energy variation of the ATP hydrolysis reaction is ΔGº’ = -30.5 kJ / mol ATP + H2O ⇄ ADP + Pi In red blood cells, when the concentration of Pi is 1.6 mM, the real change in energy free is ΔG = - 50'2 kJ / mol. a) Calculate under these conditions what is the ratio [ATP] / [ADP] in the red blood cells. b) Determine the equilibrium constant K 'of the reaction outlined above. c) If the ADP concentration were 0.2mM, what would be the effective concentration of ATP corresponding to equilibrium.
