Key Differences Between Respiration and Combustion
Respiration and combustion are both chemical reactions involving the oxidation of substances to release energy. While both processes share similarities, they differ significantly in their mechanisms, purposes, and outcomes.
Respiration is a biological process by which living cells convert glucose and oxygen into carbon dioxide, water, and energy (ATP). It occurs at moderate temperatures and is vital for sustaining life.
Combustion is a chemical reaction involving substances (usually fuels) rapidly reacting with oxygen, producing heat, light, carbon dioxide, and water. It usually occurs at high temperatures and is utilized for energy production.

FAQs on Difference Between Respiration and Combustion
1. What is the main difference between combustion and respiration?
Combustion is a rapid chemical reaction that releases energy as heat and light, while respiration is a slow biological reaction producing energy for cellular activities.
2. What is the difference between burning and respiration?
Burning is a fast combustion reaction producing heat and light, whereas respiration is a controlled biological process producing energy in living organisms.
3. Is respiration a combustion reaction?
Respiration is similar to combustion as both involve oxidation; however, respiration is a controlled biological process at moderate temperatures, unlike combustion.
4. What is the similarity between respiration and combustion?
Both respiration and combustion require oxygen and produce carbon dioxide, water, and energy.
5. What is the difference between respiration and breathing?
Respiration is a chemical process producing energy within cells, while breathing is the physical act of moving air in and out of the lungs.
6. Is rusting a combustion?
Rusting is not combustion but an oxidation reaction involving iron, moisture, and oxygen, occurring slowly without fire.
7. Is respiration endothermic or exothermic?
Respiration is an exothermic reaction, releasing energy in the form of ATP.
8. What are the different types of combustion?
The types of combustion include complete combustion, incomplete combustion, rapid combustion, spontaneous combustion, and explosive combustion.
9. What are examples of combustion in everyday life?
Examples include burning wood for heat, gasoline in vehicles, natural gas for cooking, candles, and fireworks.
