Question

we know that combustion and respiration produce same products but they differ give reason​

Answer 1

Answer:

Combustion, or burning,[1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion does not always result in fire, because a flame is only visible when substances undergoing combustion vapourise, but when it does, a flame is a characteristic indicator of the reaction. While the activation energy must be overcome to initiate combustion (e.g., using a lit match to light a fire), the heat from a flame may provide enough energy to make the reaction self-sustaining.

Answer 2

Answer:

Cellular Respiration and Burning (Combustion): Cellular respiration resembles ordinary combustion or burning in the breakdown of chemical bonds, use of oxygen, production of carbon dioxide, and release of energy, but there are some fundamentaldifferences between the two processes.
