What would be the concentration of pyrophosphate that would remain in equilibrium without hydrolyzed when, by the action of inorganic pyrophosphatase, the concentration of orthophosphate was 20 mM. (∆Gº’ pyrophosphate hydrolysis = - 30.5 kJ / mol)
The catalytic efficiency of many enzymes depends on pH. Chymotrypsinshows a maximum value of kcat/KM at pH 8. Detailed analysis shows thatkcat increases rapidly between pH 6 and 7 and remains constant at higherpH. KM also increases rapidly between pH 8 and 10. Suggest explanationsfor these observations.
Assume that in a certain cell, the ratio of products/reactants or Keq = 614.9 (Keq is dimensionless) for the reaction Glucose + ATP <> Glucose-6-P + ADP, at a particular instant, the concentrations of each compound were Glucose =4.3M, ATP =10.5M, ADP =17.3M and G-6-P =23.5M.
