Question

Why is respiration an exothermic process?​

Answer 1

because it releases energy during this process, as glucose combine with oxygen to form Co2 and H2o with release of energy

Answer 2

a chemical reaction in which heat is given out is called exothermic reaction

when we take food then the glucose split into H2O + O2 + heat

(respiration splitting up of glucose)

that's why respiration consider as an exothermic reaction
