What is the similarity between combustion and respiration?
Answer and explanation
Correct answer: Both are exothermic oxidation reactions.
In combustion, a substance reacts rapidly with oxygen and releases energy as heat and often light. In respiration, glucose undergoes controlled, slow oxidation, and the released energy is mainly captured in ATP. Therefore, both are exothermic oxidation processes, although respiration does not occur with a flame like combustion.
