Consider the formation of a dimeric protein 2P ->P2 At 25.0 °C , the enthalpy of the reaction is 17 kj/mol and the entropy of the reaction is 65 j/kmol. Is the dimerization favored at this temperature ? Thermodynamically speaking, explain/support your answer. Show work.
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.
3) The enzyme aldolase catalyzes the conversion of fructose-1,6-diphosphate (FDP)to dihydroxyacetone phosphate (DHAP) and glyceraldehide-3-phosphate (G3P).

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.
