Answer #1

The reasons which makes ATP hydrolysis release high amount of free energy as the orthophosphate molecular ion which is stabilized by multiple resonance structures making products more stable than the reactants which are ADP +Pi and ATP respectively. The second reason is that the electronic repulsion between 3 phosphate group also contributes to the high energy and instability which is stabilized by release of energy and Pi through the hydrolysis.

Subject: Cell Biology Why do some books state that the standard free energy for the hydrolysis of the gamma-phosphate group (the one furthest from the ribose) of ATP is different from the standard free energy change for the hydrolysis of the beta phosphate group (the middle phosphate group)? (my textbook shows the same standard free energy change for the hydrolysis of these two groups and that the textbook uses kcal/mol as the unit for free energy (some textbooks use kJ/mol)).

It’s demanding to measure the standard free-energy change associated with the hydrolysis of ATP because the minute amount of ATP remaining at equilibrium is difficult to measure accurately. The value of ΔG'º can be calculated indirectly, however, from the equilibrium constants of two other reactions (the first of which should look familiar) that have less favorable equilibrium constants: glucose-6-phosphate + H2O à glucose + Pi                    Keq'=270 ATP + glucose à ADP + glucose-6-phosphate   Keq'=890 Using this information, calculate ΔG'º for...

The standard free energy change for ATP hydrolysis is -30.5 kJ/mol. Therefore, the free energy change for this reaction in a cell in which the concentration of ATP, ADP, and Pi are 3.1 mM, 2.2 mM and 6.8 mM, respectively, and assuming a physiologically relevant temperature (37 °C), is: Answer -44.25 kJ/mol explain

Cellular ATP hydrolysis does not always release exactly the same amount of energy. Provide a thermodynamic explanation for this observation. (hint, do your reading in Cell Bio by the numbers!) In the conditions of a muscle cell recovering from severe exercise, would you expect the hydrolysis of one mole of ATP molecule to produce MORE or LESS energy? Circle one and explain your reasoning.

Protein synthesis requires energy in the form of ATP and GTP. Two high-energy phosphate bonds (from ATP) fuel the formation of one aminoacyl tRNA. Formation of the initiation complex requires energy from one GTP. Delivery of each new tRNA to the Asite requires one GTP. Termination requires the hydrolysis of one GTP.   Based on this information, the table of codons, and your understanding of the processes of Activation, Initiation, Elongation, and Termination, answer the following questions. How many high energy...

The molecular process that makes muscle contraction possible is that ATP binds to myosin, which releases the energy needed to make the muscle contract. In this problem, we will examine the quantities of energy involved in this process. Part 1 The reaction of ATP hydrolysis catalyzed by myosin (M) occurs in several steps*: M + ATP → M·ATP M·ATP → M·ADP·Pi M·ADP·Pi → M·ADP + Pi (aq) M·ADP → M + ADP * T. Kodama & R.C. Woledge, "Enthalpy Changes...

The standard free energy that is required for the sodium-potassium ATPase to pump two K+ ions into the cell and three Na+ ions out is +43.8 kJ/mol but the standard free energy change of hydrolysis of ATP is only -32 kJ/mol. This apparent imbalance of free energy can be accounted for because: A) the movement of Na+ ions is down the concentration gradient . B) the movement of K+ ions is down the concentration gradient. C) the free energy provided...

In some cells glucose can be taken up by two different transport systems: facilitated diffusion and glucose/proton symporter. a) Why is glucose not taken up by passive diffusion but by means of permeases? Describe the composition and structure of the permeases. b) Distinguish between facilitated diffusion and carbohydrate/proton symporter. The energy used to promote the active transport is the sum of the concentration-dependent energy (R∙T∙lnK) and the electrical work (z∙F∙ΔV). This process is usually linked directly or indirectly to ATP...
