Question

Respiration is the same process as combustion . But it is not combustion

Answer 1

Respiration is a biological process under biological control but combustion is a chemical process and it is uncontrolled process.respiration takes place in normal temperature and a slow process so energy is liberated in several steps and remain stored in the form of ATP wheras combustion is a fast process in which the energy is liberated only in one step resulting in increase in temperature and production of fire. in respiration oxygen is employed as an oxidant only at the end of the reaction.but in combustion oxygen is directly used in the process.

Answer 2

Respiration is the process where oxygen is inhaled and carbon dioxide is exhaled and the combustion is the burning of substances in the presence of oxygen
