How do you show that respiration is a chemical change?

During respiration, energy is released.Respiration is a form of oxidation.

Glucose is oxidised to CO2 and H2O (along with release of energy) at the cells by the oxygen from air we breathe in.

      C6H12O6 + 6O2 = 6CO2 + 6H2O+energy

Since glucose is converted into new products with different composition, respiration is a chemical change.
