About 0.9 kg of CO2 is produced per day per human. Assume that all of this CO2 comes from the metabolism of glucose as shown in the following reaction:
C6H12O6(s) + 6 O2(g) → 6 CO2(g) + 6 H2O(l) ΔH = –2803 kJ/mol
About 75% of the energy generated is used for daily basic functions and 25% is used to maintain electric potential in cellular functions. Calculate the energy generated for daily basic functions in kW based on the CO2 produced per day.
