In cellular respiration, what is the relationship between the energy content of the reactants (glucose and O2) and products (CO2 and H2O) ?

A) The energy content of the reactants (glucose and O2) must equal the energy content of the products (CO2 and H2O) .
B) The energy content of the reactants (glucose and O2) must be greater than the energy content of the products (CO2 and H2O) .
C) The energy content of the reactants (glucose and O2) must be less than the energy content of the products (CO2 and H2O) .
D) There is no relationship between the energy content of the reactants (glucose and O2) and the energy content of the products (CO2 and H2O) .
E) There is no relationship between O2 and H2O, but the energy content of glucose is less than that of CO2.

Energy Content

The amount of energy, typically measured in calories or joules, that is contained in a food or fuel source, indicating its potential to do work or produce heat.

Reactants

Substances initially present in a chemical reaction that are consumed during the reaction to make products.

Products

Substances resulting from a chemical reaction, process, or biological pathway.

Final Answer :
B
Explanation :
In cellular respiration, the energy content of the reactants (glucose and O2) is greater than the energy content of the products (CO2 and H2O) because some of the energy is released as heat. This is known as the "heat of combustion" and is calculated as the difference between the energy content of the reactants and the products. Therefore, B is the correct choice.
