Calculate the standard free energy change (ΔG°') for the reaction catalyzed by the enzyme aspartate amino transferase (K'eq = 6.8) using the given equilibrium constant for the reactions at 25°C and pH 7.0.

Why is iron generally harder and have higher yield strength (σy) when it is alloyed with carbon? a) Carbon forms an interstitial solid solution in iron and Fe-C bonds are very strong. b) Carbon forms an interstitial solid solution in iron and the C atoms bind dislocations. c) Carbon forms a substitutional solid solution in iron and Fe-C bonds are very strong. d) Carbon forms a substitutional solid solution in iron and the C atoms bind dislocations. e) Carbon is the base element for diamond, which is very hard.

Glycolysis is the process by which glucose is metabolized to lactic acid according to the equation C6H12O6(aq)2C3H6O3(aq) G=198 kJ at pH 7.0 and 25°C Glycolysis is the source of energy in human red blood cells. In these cells, the concentration of glucose is 5.0103 M, while that of lactic acid is 2.9103 M. Calculate AG for glycolysis in human blood cells under these conditions. Use the equation G=G+RT In Q, where Q is the concentration quotient, analogous to K.
