H. H. CN H.Question: A. To explore the consequences of coupling ATP hydrolysis under physiological conditions to a thermodynamically unfavorable biochemical reaction, consider the hypothetical transformation X⟶Y, for which Δ?′°=20.0 kJ/mol. What is the ratio of [Y]/[X][Y]/[X] at equilibrium? B. Suppose XX and YY participate in a sequence of reactions during which ATP is hydrolyzed to ADP and Pi. The overall reaction is X+ATP+H2O⟶Y+ADP+Pi Calculate [Y]/[X] for this reaction at equilibrium. Assume that the temperature is 25.0 °C and the equilibrium concentrations of ATP, ADP, and Pi are 1.00 M each. C. We know that [ATP], [ADP], and [Pi] are not 1.00 M under physiological conditions. Calculate [Y]/[X] for the ATP‑coupled reaction when the values of [ATP], [ADP], and [Pi] are those found in rat myocytes. Metabolite Concentration in rat myocytes (M) ATP 8.05x10-3 ADP 0.93x10-3 Pi 8.05x10-3P3D.2 In biological cells, the energy released by the oxidation of foods is stored in adenosine triphosphate (ATP or ATP“).The essence of ATP's action is its ability to lose its terminal phosphate group by hydrolysis and to form adenosine diphosphate (ADP or ADP): ATP* (aq) + H,O() → ADP* (aq) + HPO (aq) + H,O*(aq) At pH = 7.0 and 37°C (310K, blood temperature) the enthalpy and Gibbs energy of hydrolysis are A,H =-20kJ mol and A,G=-31 kJ mol", respectively. Under these conditions, the hydrolysis of 1 mol ATP“(aq) results in the extraction of up to 31kJ of energy that can be used to do non- expansion work, such as the synthesis of proteins from amino acids, muscular contraction, and the activation of neuronal circuits in our brains. (a) Calculate and account for the sign of the entropy of hydrolysis of ATP at pH = 7.0 and 310K. (b) Suppose that the radius of a typical biological cell is 10µm and that inside it 1x 10ʻ ATP molecules are hydrolysed each second. What is the power density of…
