Question

why is respiration considered an exothermic reaction

Answer 1

it is so because respiration is a process of oxidative broke down of food to get energy.

exothermic reaction is a reaction which gives energy out

so in respiration energy is given out

Answer 2

Exothermic reaction are those reaction in which energy is evolved.

Respiration is considered as exothermic reaction because during the process of respiration energy is evolved . For ex. If we eat potato it contains large amount of glucose . These glucose get oxidised with oxygen and release energy in the form of ATP molecule .

Hence respiration is considered as exothermic reaction
