Question 10

Why is respiration considered an exothermic reaction? Explain.

Answer 1

Respiration is considered as an exothermic reaction because in this process, oxidation of glucose takes place, producing large amount of heat energy. The reaction involved is-

${\text{C}}_6{\text{H}}_{12}{\text{O}}_6\text{(aq)}+6{\text{O}}_2\text{(g)}\to 6{\text{CO}}_2\text{(g)}+6{\text{H}}_2\text{O(l)}+\text{Energy}$
