Final answer:

In the equation C6H12O6 + 02, glucose and oxygen contain more energy compared to carbon dioxide and water in the equation CO2 + H2O.

Step-by-step explanation:

The set of molecules in equation b) C6H12O6 + 02 (Glucose and oxygen) contains more energy compared to equation a) CO2 + H2O (carbon dioxide and water).

Glucose (C6H12O6) is a carbohydrate and a source of energy in living organisms. In the process of cellular respiration, glucose reacts with oxygen to produce carbon dioxide and water, releasing a large amount of energy.

On the other hand, in equation a), carbon dioxide (CO2) and water (H2O) are products of a combustion reaction where a fuel is burned in the presence of oxygen. While energy is released during combustion reactions, they typically produce less energy compared to the breakdown of glucose in cellular respiration.
