delta G' hydrolysis within a cell is MORE THAN NEGATIVE delta G0
The figured ∆G for the hydrolysis of one mole of ATP into ADP and Pi is −7.3 kcal/mole (−30.5 kJ/mol). Since this count is valid under standard conditions, it would be normal that an alternate esteem exists under cell conditions. Actually, the ∆G for the hydrolysis of one mole of ATP in a living cell is twofold the esteem at standard conditions: 14 kcal/mol (−57 kJ/mol).
Do you expect that delta G' for ATP hydrolysis within a cell is usually more or...
If the delta G°¢ for ATP hydrolysis is –31 kJ/mol and the delta G°¢ for phosphoenolpyruvate hydrolysis is –62 kJ/mol, what is the DG°¢ for the phosphorylation of ADP by phosphoenolpyruvate? A) –93 kJ/mol B) –31 kJ/mol C) +31 kJ/mol D) +93 kJ/mol E) none of the above Please provide explanation of how to solve this question, if possible include the reactions, thank you so much
ATP hydrolysis and the endergonic reaction that is coupled to it are usually represented as two separate equations. Explain why, if these where indeed two separate reactions, ATP hydrolysis will not be able to power the endergonic reaction? Does the answer have anything to do with the fact that ATP, although exergonic, is an incredibly stable molecule and will react slowly without the presence of an enzyme?
Since AMP can also be hydrolyzed to release energy, why do cells bother to use ATP (which requires the cell to have more phosphate) to power cellular reactions? Question 1 options: a. ATP fits better into enzymes. b. ATP hydrolysis releases more energy than AMP hydrolysis. c. ATP stores for a longer time than AMP. d. Cells have more than enough phosphate, and it serves few roles anyway.
er at initial change (AG The standard free energy change (AG) for ATP hydrolysis is -30.5 kJ/ mol ATP, ADP, and I are mixed together at initial concentrations of 1 M each then left alone until the reaction below has come to equilibrium. For each species (ie. ATP. ADP and P.) indicate whether the concentration will be equal to 1 M, less than 1 M, or greater than 1 M after the reaction had reached equilibrium. Explain why. ATP +...
Do expect the cell to produce more ATP from one glucose molecule or from one fatty acid molecule? Explain your answer. Indicate whether the following statements are true or false. If a statement is false, explain why it is false The proteins of the electron-transport chain remove a pair of high-energy electrons from the cofactors, NADH and FADH_2, after which the electrons move across the inner mitochondrial membrane to maintain the voltage gradient. Gluconeogenesis is a linear reaction pathway that...
7) Why do hydrolysis reactions occur more readily in solution than dehydration reactions? A) Hydrolysis reactions increase G, or Gibbs free energy of the system, B) Hydrolysis reactions are endergonic and increase entropy of the system. C) Hydrolysis reactions are exergonic and decrease entropy of the system. D) Hydrolysis reactions are exergonic and increase entropy of the system. 8) How do cells use the ATP cycle illustrated in the figure? AAA W A) Cells use the cycle to recycle ADP...

If the cell had high [ATP] and low [AMP], what would you expect to happen to the following processes (i.e. process vs. not proceed)? What causes them to process/not proceed and be sure to address any enzymes involved. Glycolysis Gluconeogenesis Glycogen breakdown Glycogen synthesis
3b) Would you expect rotenone to be more, less or equally
poisonous as carbon monoxide? Explain you answer. (10pt)
3. In the lab, metabolic poisons can be used to study ATP synthesis and oxygen consumption. The action of several metabolic poisons is given in the table below: Poison Oligomycin Carbon monoxide 2,4-dinitrophenol (DNP) Rotenone Action Binds and blocks the proton channel in ATP synthase Inhibits cytochrome oxidase Binds protons and moves them down their electrochemical gradient Blocks electron transfer at...
