In anaerobic cells glucose C6H12O6 is converted to lactic acid: C6H12O6 → 2CH3CH(OH)COOH. The standard enthalpies of formation of glucose and lactic acid are –1274.45 and –694.04 kJ/mol, respectively. The molar heat capacities (at constant pressure) for glucose and lactic acid are 218.86 and 127.6 J/mol K, respectively.

(4.a) Calculate the molar enthalpy associated with associated with the formation lactic acid from glucose at 298 K.

(4.b) What would the quantity in part (4.a) be if the reaction proceeded at a physiological temperature of 310 K?

(4.c) Based on your answers in parts (4.a) and (4.b) how sensitive is the enthalpy of this reaction to moderate temperature changes?

In the Potter process, sucrose is converted to glucose and fructose: C12H22O11 + H2O → C6H12O6 + C6H12O6 The combined glucose and fructose is called inversion sugar. Fresh feed flows at a rate of 0.5 ton/min containing 70% sucrose and 30% water by mass. The fresh feed is combined with a recycle stream so that the stream entering the reactor contains 5% inversion sugar by mass. If 87% conversion of sucrose occurs, determine: A. the recycle stream flow B. the...

When O2 is added to an anaerobic suspension of cells consuming glucose at a high rate,...

When O2 is added to an anaerobic suspension of cells consuming glucose at a high rate, the rate of glucose consumption drops significantly as the O2 is consumed; the accumulation of lactate also ceases. First observed by Louis Pasteur in the 1860s, this effect is characteristic of most cells capable of aerobic and anaerobic metabolism. a) Why does lactate cease to accumulate upon addition of O2? b) Why does the rate of glucose consumption decrease? c) What is the mechanistic...
