How is the combustion of propane similar to cellular respiration how are they different?

The combustion of propane and cellular respiration both involve the oxidation of a fuel source to release energy. In both processes, oxygen is used, and carbon dioxide and water are produced as byproducts. However, combustion of propane is a chemical reaction that occurs rapidly, releasing energy in the form of heat and light, while cellular respiration is a metabolic process that occurs in living organisms, converting stored energy in glucose into usable energy (ATP) more gradually and efficiently. Additionally, cellular respiration is a series of enzymatic reactions, whereas propane combustion is a straightforward chemical reaction.
