Webreactions can adequately describe coupled (or auxiliary) enzyme assays if the three conditions are met: (i) the rate of the non-observable enzyme is con-stant, (ii) the coupled enzyme reactions are irreversible, and (iii) the indicator reaction has a short-lived intermediate with a concentration smaller or equal to its Michaelis constant. WebThe coupled reaction exhibits a negative free energy change and is spontaneous: ZnS(s) + O2(g) → Zn(s) + SO2(g) ΔG° = 201.3kJ + − 300.1kJ = –98.8kJ This process is typically carried out at elevated temperatures, so this result obtained using standard free energy values is just an estimate. The gist of the calculation, however, holds true.
Coupled Reaction in Bioenergetics - Biology Discussion
WebATP-Coupled Reaction Process: Energy is either absorbed or released when a reaction occurs. This depends on the relative abilities to break bonds and forming bonds. Two important reactions occur in ATP coupling,namely, exergonic and endergonic reactions. Exergonic reaction: o Energy is emitted into the surroundings in an exergonic reaction.

WebThe overall reaction is X + ATP + HO — Y+ ADP + P Calculate [Y]/ [X] for this reaction at equilibrium. Assume that the temperature is 25.0 °C and the equilibrium concentrations of ATP, ADP, and P; are 1.00 M each. [Y]/ [X] = We know that (ATP], [ADP], and [Pi] are not 1.00 M under physiological conditions.
