Question

A and B both please

The reaction of an organic compound with O_2 to generate CO_2 and H_2O is called a combustion reaction. The combustion of glucose takes place in living systems, but it also may be earned out in the laboratory in the same manner octane is combusted in a car engine. Is there a difference in the amount of energy produced by these two methods of combusting glucose? Explain your answer. In terms of energy production, what is the major difference in these two methods of combusting glucose?

Explanation / Answer

a) Combustion of glucose in living system:

C6H12O6 + 6O2 -------> 6CO2 + 6H2O + 2815 kj/mol

Combustion of glucose in laboratory:

C6H12O6 + 6O2 -------> 6CO2 + 6H2O + 2815 kj/mol

No, there is no difference in the amount of energy released during the combustion of glucose in living system or in laboratory. So, energy released due to combustion of glucose inside the cell is overall the same amount of energy that would be released if we simply burn the glucose in laboratory.

b) Major difference between these two methods of combustion are:
