Difference between respiration and combustion

1.	Difference between respiration and combustion
Answer» \tRespirationCombustionRespiration is a cellular processCombustion does not occur inside the living cellRespiration is a controlled biological processCombustion is an uncontrolled processEnergy is released in a stepwise manner with different biochemical reactionsEnergy is released in a single stepLess than half of energy is liberated as heatEnergy is released as heat. It can get hot enough to produce incandescent light.Temperature is not allowed to rise and controlled otherwise it can damage the cellThe temperature during combustion is very high.Adenosine triphosphate is formed during this process. On breakage of the molecular bond, energy is released for physiological processes.Adenosine triphosphate is not formed.Oxidation occurs at the end of the reaction between oxygen and reduced coenzymes in the electron transport chainSubstrates are directly oxidised in the combustion processEnzymes are required for the process of respirationEnzymes are not required for combustion as it is a non-cellular processExample: Aerobic respirationExample: Combustion of oxygen and hydrogen into water vapour\t
